Hoval’s extensive product range includes the following:

Gas condensing boilers
The UltraGas® 2 is Hoval’s latest generation of gas condensing boilers for heating and hot water generation. The boiler is available with output ratings ranging from 125 kW to 1550 kW, and 250 kW to 3100 kW as a double boiler. Based on the first generation of UltraGas® condensing boilers – which have been tried and tested for over 20 years – the successor model boasts a patented Hoval TurboFer® heat exchanger for even greater efficiency, combined with a future-proof and compact design. The gas boiler can also operate on biomethane and hydrogen, equipping it for the ongoing energy transition from gas to biomethane and for a hydrogen-powered future – and setting a new benchmark for renovation and new-build projects including multiple-occupancy buildings, small commercial properties, industrial sites and large plants.

Indoor Climate Systems
The Hoval indoor climate system creates a comfortable climate in large interior areas while ­minimising energy consumption. Unlike centralised systems, it has a modular structure in which one system contains multiple and possibly different indoor climate units. This guarantees adaptability and flexibility in all phases: planning, installation, operation and maintenance.
Hoval RoofVent® units are roof ventilation units for supplying fresh air and removing extract air.
Hoval TopVent® units are for recirculation or supply air for heating and cooling with mixed air or fresh air.

Biomass boilers
Hoval pioneered the transformation of wood burning technologies to bring the combustion efficiencies of biomass boilers much closer to those of fossil fuel burning boilers. At the same time, ease of use has been greatly enhanced through the introduction of automated features for activities such as fuel supply and re-ignition. The Hoval STU is a modulating high efficiency skid mounted commercial wood pellet boiler fitted with external stoker and fuel pick-up system. The STU ranges from 200kW to 975kW. Simple maintenance and low emissions have made this boiler a popular choice.

Thermal storage vessels
The EnerVal primary mild steel buffer vessel is available from 100 to 6000 litres.
EnerVal has a maximum working pressure of 3 bar g, whilst the EnerVal G has a maximum working pressure of 6 bar g.

Thermal insul. Up to 180mm

Max oper. temp. Up to 95°C
Larger vessels available on request.

Air Source Heat pumps
The Belaria® fit is a modulating air/water heat pump for heating and cooling in two output sizes for outdoor installation.
Belaria® fit (53): up to 853 kW
Belaria® fit (85): up to 1.4 MW

With Belaria® fit, efficient systems with a high proportion of renewable energies can be planned. As a monovalent system, up to 1.4 MW is possible. Bivalent hybrid systems can even supply up to 4 MW - depending on the required proportion of renewable energies.

Hoval Extends Energy-Saving Solutions


Hoval has announced the continued expansion of its range of energy-saving solutions with new products designed to improve energy efficiency and reduce carbon emissions whilst optimising cost of ownership.

A case in point is the new range of Belaria® fit air/water heat pumps, specifically designed for systems with high outputs and a high proportion of renewable energies. Belaria® fit delivers efficient heating, cooling and domestic hot water production at the same time and can be used on its own or as part of a hybrid system.

Belaria® fit uses advanced, modulating inverter technology that enables continuous adjustment from 40-100% of load, ensuring consistently optimum energy efficiency in applications with variable demand. This is combined with use of R32 refrigerant, ideally suited to the UK's temperate climate. Consequently, systems with Belaria® fit are considered sustainable and are eligible for subsidies.

Up to 16 Belaria® fit units can be combined in a cascade configuration, enabling outputs into the megawatt range. Belaria® fit is also well suited to use in a hybrid configuration, such as alongside a gas condensing boiler for use at peak demand to provide attractive price/performance ratios. The units are also easily retrofitted to existing heating systems.

Also joining the Hoval portfolio is a new range of TopVent® decentralised roof ventilation units, specifically designed to meet the needs of large 'shed' like buildings – especially suitable for applications where undisturbed operation within the building is of paramount importance.

Disruption in the space is avoided because the units are installed completely from the roof, so that the only work in the building is hydraulic and electric connections. Moreover, all serviceable components can also be accessed from the roof, so that regular maintenance and service work can be carried out without disturbance to the activities below. Thus, maintenance is easier to schedule and downtime is avoided.

The inherent flexibility of the TopVent range supports Hoval's zone-based control concept, whereby combining different types of unit ensures that each space – or each zone within a large space – can be controlled independently of other units in spaces/zones.

All Hoval products are backed by a team of experienced engineers to advise on design and product selection and support the customer from start to finish – and through ongoing operation.

New generation UltraGas boiler

Earlier this year Hoval launched their UltraGas® 2 boiler.

The latest generation of gas condensing boilers brings even higher efficiency to the popular features of the first UltraGas® generation. UltraGas® 2 models are available with output ratings from 125kW to 1550kW (250kW to 3,100kW as a double boiler), and in 10 bar versions for 720, 1100 and 1550kw units.

UltraGas® 2 boilers are designed for easy integration with existing systems and have the ability to work with any flow/return temperature difference (Delta T) for optimum flexibility. With a maximum operating temperature of 95Deg.C they are ideal for use in district heating/heat networks applications, and in future will also be able to operate on biomethane and hydrogen.

At the heart of the new design is the patented Hoval TurboFer® heat exchanger, which combines a unique design with special injection technology to generate turbulence on the heating gas side. This turbulence increases heat transfer and boosts efficiency by as much as 20% compared to conventional gas boilers.

Other UltraGas® features include high and low temperature return flow, a large water capacity, the Ultraclean® combustion system and the TopTronic® E system controller.

Thanks to the standardised Hoval TopTronic® E controller, UltraGas® 2 boilers can be easily combined with any type of heat generator and solar energy system to create an integrated heating system where all the components work together to optimise efficiency.

Ease of installation has been a key element in the design, so there is no need for system components such as a circulating pump or hydraulic separator. The amount of pipework in the TurboFer® heat exchangers has also been reduced to minimise weight, resulting in a lightweight, compact design. For example, models up to 450kW are less than 800mm wide and will fit though a standard door, while the small footprint means that larger models take up half the space of other gas condensing boilers.

Long, reliable performance with Hoval’s STU biomass boilers

Hoval’s UK-manufactured STU wood pellet biomass boilers have been engineered to deliver long, reliable and efficient service with very low particulate emissions for agricultural, horticultural and many other applications. Robust construction combined with advanced Flametronix® microprocessor-driven combustion controls ensure that STU boilers avoid the frequent breakdowns associated with other biomass boilers – for long-lasting peace of mind.

As holder of a Royal Warrant to HM The Queen as boiler manufacturers and engineers, Hoval manufactures its boilers to the highest standards for long-lasting reliability. STU biomass boilers are designed and manufactured at Hoval’s factory in Newark, Nottinghamshire from high quality carbon steel with a fully insulated boiler frame. A robust cast steel fuel retort is specially designed to ensure controlled firing of the pellets, whilst burn-back protection is assured via advanced fuel feeding control, thermally activated water dowsing of the fuel feed auger and a fire-rated damper valve with twin proximity switches.

Remote, online monitoring of performance as standard ensures that servicing schedules are aligned to boiler run-hours to maintain optimum reliability and efficiency, and that any fluctuations in performance are quickly identified and investigated.

Independent testing has confirmed efficiencies of up 92% using EN+ standard wood pellet fuel, achieved through an intelligent combination of inverter-controlled fuel feed augers and an extremely responsive lambda probe.

Hoval STU boilers are available in heat capacities from 200kW to 975kW and are skid-mounted for ease of siting and installation. They are fitted with an external stoker and fuel pick-up system as standard – or with a flexi-worm screw feed for connection to remote fuel storage if required.

UltraGas condensing boilers from Hoval


Hoval UltraGas condensing gas boilers are available in capacities from 15kW to 2300kW – complete with common flue and optional pipework/header kits.

Independent testing (to DIN EN 676) confirms the average NOx emissions of the boilers are less than 40 mg/kWh – achieving the maximum BREEAM rating of three points relating to NOx emissions. Net efficiencies of up to 109.9% are also achieved, when tested to the requirements of the European Boiler Efficiency and Gas Appliance Directives, with CO levels of 10 mg/kWh.

Featuring Hoval’s Ultra Clean combustion system, the boilers use a modulating pre-mix down-firing burner with up to 12:1 turndown and a stainless steel combustion chamber with a single pass aluFer tube heat exchanger. The aluFer tubes are also made of stainless steel with an aluminium alloy finned internal surface to provide a high surface area for heat exchange.

All UltraGas boilers have a connection at the rear to accept a ducted fresh air supply for room-sealed applications. They are also fitted with two return connections for high and low temperature circuits.

The operation of each boiler can be controlled via a 0-10v input signal (by the addition of an optional interface module). This allows BMS control of either the burner firing rate or the boiler operating temperature set point. Optional TopTronic controllers (one or two) can be provided for enhanced control features including sequencing for modular installations and system control.

Ongoing support

Hoval actively encourages an ongoing relationship with clients to ensure ongoing support for the life of the boiler. The company’s service department provides technical support for clients, specifiers and installers.

Hoval launches Large Space Heating system for warehouses

Hoval has launched a modular, scalable solution for heating and ventilating warehouses and other ‘shed’ type buildings of any size and height, providing significantly improved control of thermal stratification compared to conventional systems. Providing the best features of both centralised and decentralised systems, the Hoval Large Space Heating system simplifies planning and tendering whilst also reducing project implementation times.

The system is based on a three-module concept configurable depending on requirements; the UltraGas condensing gas boiler feeding TopVent units for recirculation or RoofVent units if air changes are required. All of these products are controlled by the TopTronic C zone control system – all fully ErP 2018 compliant.
If heat pumps are the approach on the project instead of gas boilers then RoofVent RP and TopVent TP are decentralised units combined with air source heat pumps to provide heating or cooling. Existing heating or cooling solutions from other manufacturers can also be interlinked with RoofVent and TopVent.

Thermal stratification is minimised by the Air Injector vortex air distributor in TopVent and RoofVent units, which enables easy adjustment of the air stream range from 4m to 25m and regulates the scatter angle (induction) of the air stream as a function of the mounting height. Temperature stratification is thereby limited to 0.15K per mounting height metre (K/m) – compared with up to 1.0 K/m in conventional systems.

In conjunction with temperature- and time-based zone control, the heating times and hall temperatures can be optimally adapted to the logistical and energy-related requirements. Due to the high ventilation efficiency of the TopVent recirculation heating units, the Hoval solution makes do with fewer units and lower air flow rates than conventional recirculation heaters. This reduces investment, installation and operating costs.

Hoval brings greater simplicity to sophisticated heating control

Hoval’s TopTronic® E is an entirely new system controller for Hoval boilers, calorifiers, heat pumps and other heat sources with the ability to control one or multiple conventional and low carbon heat sources with a single unit or in cascades with up to 8 units.

Designed from the ground up it delivers a completely new level of simplicity, modularity, connectivity and user experience without compromising on control functionality. As such, it eliminates the inconvenience and risk of trying to work with different controllers for different appliances and system configurations.

Featuring ‘plug and play’ modular hardware, TopTronic® E allows easy extension of an existing system with additional Hoval components (e.g. solar thermal panels or an additional water heater). It can also operate alongside the new TopTronic® Supervisor within a fully scalable system for the real-time visualisation, monitoring and optimisation of district heating networks.

For ease of remote monitoring and system optimisation, TopTronic® can be accessed via an integral internet connection through a simple computer interface that also informs the user when routine or reactive maintenance is required. It will also integrate with a building management system using ModBus or KNX interfaces and is ‘smart grid’ ready.

New high efficiency low NOx steel shell boilers from Hoval

Hoval has introduced two new models to its range of high efficiency, low NOx steel shell boilers; the Max-3 E and the Max-3 condens E. Each model is available in four sizes in outputs up to 6,800kW in gas and dual fuel options. Key features include return inlets with injection effect to ensure return water is heated evenly – avoiding condensation on the flue surface and extending service life.

A low NOx burner is supplied as standard in both models to ensure compliance with the forthcoming Medium Combustion Plant Directive (MCPD), which will apply to boilers commissioned after December 2018. This is combined with three-pass technology in the Hoval Max-3 E to reduce emissions even further, with retarders in the third pass tubes to improve heat transfer and efficiency.

The Hoval Max-3 condens E also uses a three-pass heat exchanger design, combined with an integrated flue gas condensing heat exchanger with a large heat transfer surface to increase the rate of condensation. The large tube diameter of the gas heat exchanger also reduces hydraulic resistance so that a smaller pump can be used (compared to boilers with a narrower tube).

Both boiler models are delivered assembled and ready to use, complete with full thermal insulation and aluminium cladding, as well as flexibly adjustable connections for ease of installation. The large, thermally-insulated boiler door ensures easy access for cleaning and maintenance, and the tube nest area of the second pass can also be easily accessed thanks to the large combustion and reversal chambers.

Managing IAQ with optimum efficiency

As buildings become more tightly-sealed to improve energy performance it is no longer practical or acceptable to rely on natural ‘leakiness’ to maintain indoor air quality (IAQ). Architects, therefore, need to ensure their buildings have in-built systems that will not only maintain good IAQ but will do so without wasting energy.

The best option is to recover as much heat as possible from the outgoing air while avoiding drying the air due to moisture escaping the building. Hoval’s HomeVent is one of the few MVHR systems to recover heat AND moisture to deliver energy-efficient draught-free ventilation and good humidity control.

HomeVent units are available with airflow rates from 150m3/h to 500m3/h.
