Heat Networks

Modutherm's comprehensive range of heat interface units (HIUs), heat stations, and commercial heat pumps are designed for fourth and fifth generation district heating networks. Our MTA Plus is the UK's best performing heat pump optimised HIU, achieving the lowest VWART scores in BESA testing (26°C high temperature, 24°C low temperature). From compact twin-plate HIUs for apartment buildings to ambient loop heat stations and commercial air source heat pumps, our heat network solutions deliver exceptional efficiency for multi-dwelling residential developments, social housing, and commercial properties across the UK.

Heat Pumps

Heat pumps provide energy-efficient heating, cooling, and domestic hot water by extracting renewable heat from the air, ground, or water. Modutherm's comprehensive range includes commercial air source heat pumps (Hybrox and AW290, 10-100kW heating, 8.6-85kW cooling), brine/water source heat pumps (Alterra WZSV and PWZSV, 5.95-17.2kW), and exhaust air heat pump water heaters (Juniper HP Plus, 200-300L). These systems are suitable for apartment buildings, hotels, schools, commercial properties, and heat network applications across the UK.

Air Source Heat Pumps

An air source heat pump (ASHP) provides energy-efficient space heating, cooling, and domestic hot water by extracting renewable heat from outdoor air. Modutherm's commercial air source heat pumps include the Hybrox and AW290 series, with heating outputs from 10-100kW and cooling capacities from 8.6-85kW. With A+++ energy efficiency ratings, these R290 heat pumps are ideal for apartment buildings, hotels, schools, and commercial heat network applications.

Brine/Water Source Heat Pumps

A brine/water source heat pump (also known as a ground source heat pump or geothermal heat pump) provides energy-efficient space heating, cooling, and domestic hot water by extracting renewable heat from the ground via geothermal probes, ground collectors, or ambient loop heat networks. Modutherm's Alterra brine/water heat pumps include the WZSV and PWZSV series, with heating outputs from 5.95-17.2kW. Achieving COPs of up to 4.92 and A+++ energy efficiency ratings, these compact heat stations include integrated 180-litre stainless steel domestic hot water cylinders. Ideal for apartment buildings, residential properties, and heat network applications where space is at a premium, they deliver exceptional efficiency from ground-sourced renewable energy.

Exhaust Air Heat Pump Water Heater

An exhaust air heat pump water heater provides energy-efficient domestic hot water by extracting heat from the air rather than generating it directly with electricity. The Juniper HP Plus is an exhaust air heat pump water heater that achieves a COP of up to 4.09, producing over four times more heat energy than the electricity it consumes – earning an A++ energy efficiency rating.

Boilers

Modutherm offers a comprehensive range of commercial boilers including wall hung and floor standing gas condensing boilers (32-1156kW) and electric boilers (36-504kW). Our Genesis range features stainless steel heat exchangers, modular configurations, and high-efficiency performance for commercial heating applications. The Genesis Eco electric boiler range delivers 99.9% efficiency for zero-carbon heating solutions. Suitable for schools, hotels, care facilities, apartment buildings, and commercial properties, Modutherm boilers provide reliable, powerful heating for new builds, refurbishments, and hybrid heating systems across the UK.
