Radiators that work well with heat pumps

The rise and rise of the heat pump is seeing the need for larger and higher-capacity radiators. Stelrad has responded to these needs by broadening its already massive range for its most popular radiators and the introduction of a wider range of vertical radiators.

Stelrad also meets the enhanced need for its K3 radiators – with three panels and three fins. These deliver 50% more heating capacity from a radiator with the same footprint as a K2 format radiator.

Low-temperature heating systems have understandably raised questions that installers and specifiers want answered. Can products used in conjunction with traditional boiler-driven heating systems be used with heat pumps? Is there anything that needs to be considered that’s taken for granted nowadays? The answer is of course yes. Specifiers and installers need to look closely at how to ensure that the heat generated is shared effectively in the new home, or the existing home that is having its heating system upgraded. In new-build housing, using a heat pump-based solution is a relatively simple solution. The heating system can be designed into the home at the outset so the installer knows the parameters in which the heating system has to operate – the method of construction, the size of the rooms, the number, type and size of doors and windows – so the heat loss calculations can be done up front and radiators sized accordingly.

At the outset, the levels of insulation can be agreed that will provide the best support for any heating system chosen, whether radiators or underfloor heating.

The key to radiators operating well in any situation is to size them properly at the design stage. This involves accurately working out heat loss calculations to achieve the necessary number of BTUs required to provide comfort heating in each room, and selecting a radiator that can provide that level of heating.

Stelrad offers a simple-to-use and free radiator sizing and heat loss calculator, along with a Renewables Advice page on its website at www.stelrad.ie. Facts and helpful information are also shared through a free CPD that is also available on its website.

So, should radiators be excluded in favour of other alternatives as some are suggesting? The answer is a resounding no. Radiators are very much “fit for the future” but, as always, correct sizing will need to be undertaken to ensure that they keep the home warm and cosy. Can radiators work well with air source heat pumps? Very definitely yes, they can – and they already are in a host of installations across Ireland.
