The benefi ts of hot water heat pumps
For installers looking to diversify their business, hot water heat pumps off er a relatively easy way to provide customers with a low carbon and energy effi cient heating solution. Craig Dolan, senior product manager at Dimplex, explains why they are ideal for both new and retrofi t projects.

Low carbon solution Installers are under increasing pressure to provide solutions to support the decarbonisation of new and existing UK homes. Hot water heat pumps (HWHPs), which use air-source heat pump technology to provide hot water to residential dwellings, are emerging as the ideal energy-effi cient solution. The incoming Future
Homes Standard and Part L regulations, introduced in 2022 and already in force, take a ‘fabric fi rst’ approach, which
s we head into the new year, households continue to be faced with energy prices, which
helps stop heat from escaping from a dwelling. As a result, the heating demand decreases in new developments, making hot water the dominant energy load in some properties. Consequently, the most signifi cant impact on cutting carbon emissions from a building’s design is producing hot water in a low carbon way. HWHPs are being increasingly

specifi ed as this innovation combines the benefi ts of heat pump technology, such as high effi ciencies and low energy use, with a more compact and easy- to-install solution. Knowledge of this well-established technology provides installers an excellent opportunity to off er a vital component of an all-electric HVAC system within a compact unit.
HWHPs are a cost-effective route to
decarbonisation and are a highly efficient way of producing hot water up to 60ºC
How they work A hot water heat pump consists of a ducted system that supplies fresh air to a small refrigeration circuit mounted on top of a water cylinder. The unit can be installed inside the property and supports up to six occupants’ hot water needs. With a hot water heat pump providing the hot water demand for a dwelling, the much smaller, seasonal space heating requirements can then be provided via direct-acting panel heating, SMART storage or a space heating heat pump, solutions currently benefi ting from the decarbonisation of the electricity grid. HWHPs are a cost-eff ective
route to decarbonisation and are a highly effi cient way of producing hot water up to 60°C. For example, the FHS and Part L-ready Dimplex
Edel HWHP has a CoP of up to 3.36 (according to EN16147), which can provide high carbon savings and means it can generate over three units of heat for every unit of electricity consumed. Importantly for installers
looking to diversify their skillset and product portfolio, HWHPs are easy to install and remove the requirement for additional skills and

qualifi cations often associated with integrating with renewable technology, such as F-gas certifi cation. The Dimplex Edel unit is delivered pre-wired and also features an in-built control for a seamless standalone solution and straightforward installation. Homeowners can also feel reassured, as the units require minimal maintenance and servicing.
Less disruption As there is no external unit, installers and homeowners alike will also benefi t from minimal disruption during installation. The compact Edel unit has a familiar appearance and footprint similar to a standard hot water cylinder, with options of 170L, 200L or 270L volume within the stainless steel cylinder, making it easier to choose where to site the hot water heat pump within a property. This simple process makes
the product suitable for everything from period homes
to new-build apartments. Further enhancing installation fl exibility, it is also suitable for installation within garages and utility rooms, for example, making it a solution that ticks every box.
Join the club Installers looking to unlock more business opportunities through HWHPs can access hands-on, face-to-face training on Dimplex products, including heat pump principles and servicing, and a course covering the Edel hot water heat pump. The Dimplex PRO Installer
Club has also been established to help installers achieve higher standards. A must for professionals seeking innovation and support, this exclusive programme is specifi cally designed for individuals and small businesses involved in purchasing and installing our products. The free membership
provides access to valuable resources, technical information, dedicated support, free product training, as well as exclusive off ers and special promotions. ◼
