nd the choice of radiators continues to grow – which reflects the importance of these heating system staples, especially as the heating sector adjusts to meet the new challenges of renewable heating systems and the arrival of the heat pump products that will provide the backbone of UK heating and hot water provision. The latest addition to the Stelrad portfolio is the Cast Iron Column range. Traditionally Stelrad has supplied steel radiators and continues to do so with more than two and a half million radiators manufactured each year. Cast iron column radiators have come into vogue again and the company aims to meet the demands of its customers at every level, so it has added a selection of Cast Iron Column radiators to its ever-widening range. They are floor standing with in-built feet for extra stability as they are significantly heavier than their steel counterparts. They are available in two heights and a wide variety of widths – a total of twenty sizes available. And as you would expect, they come with a cast iron ten-year warranty. The development of lower temperature heating
systems, utilising renewable heating appliances such as air source heat pumps - has given rise to a number of questions including where do components we have got to know and love over the
The role of radiators in the future of heating
Radiators make an everyday contribution to heating systems across the UK and Ireland with more than 90% of heating systems installed featuring radiators of one design or another.
years fit into the future of heating? Stelrad Radiators has responded forcefully to those people who claim for example that underfloor heating is the only or ‘best solution’ for heat pump installations. There is still a marked reluctance to use UFH
upstairs in new build and it can be a complex option to fit as a retrofit solution – so radiators tend to win out much of the time. Radiators heat up and cool down far more quickly than underfloor heating, something that needs to be borne in mind when selecting the best way to share heat around the home.
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 you know 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. The key to radiators operating well in any situation is to size them properly at the outset. In replacement heating systems for older
properties there are additional issues. Do we need to ditch radiators altogether and look for alternatives?
The simple answer is no. Radiators will work well with heat pumps, but you will need to increase the
