Heat Pumps

When using Econoloft for their loft conversions, many clients recognise the benefit of upgrading or replacing their heating systems at the same time. The popularity and interest in renewable energy sources have seen heat pumps become a viable and affordable alternative to the traditional boiler.

In fact, the government plans to phase out natural gas boilers by 2035 to cut our dependency on fossil fuels and heat pumps will be installed in all new properties as a matter of course. It makes sense, therefore, that when faced with renewing or replacing your current boiler, to consider moving to this future heat source.

A heat pump does exactly the same job as a boiler – heats your home. However, it draws in natural heat from the air or the ground and produces a refrigerant. Compression condenses the stored refrigerant to generate heat, which circulates to the radiators and the hot water cylinder.

The government is offering grants towards renewable heating costs for your home. Visit their website to see if you qualify. There are several heat pumps available and Econoloft experts will advise which is suitable for your home. If you want to heat your home in a way that is sustainable and energy efficient, talk to us and find out more about the future of home heating.

We have lived close to Econoloft for many years and we finally decided to extend into the loft. They were our only choice of whom we would like to use. We did get other quotes, but our minds were pretty much made up. What a great thing we did. From start to finish we were looked after, and we now have a 2 additional bedrooms and a bathroom. Older sons now have their own space with some peace and quiet. We must also mention Slawak too. He was such a lovely builder, couldn't say no when asked to do some extra little bits. The process was much easier than originally thought or we may have done it sooner. Highly recommend. Viewings available.

We used Econoloft for our loft conversion, which we absolutely love. It's the best thing we ever did and we live up there now! As with any addition to your property there were issues, mainly unexpected costs which you would always get in building work, but they were addressed and discussed as they arose. We had a wonderful joiner, who did a brilliant job with his crew. The Econoloft tiler did an exceptional job on the bathroom tiling, and we've recommended him several times to other people. From the initial consultation to completion, they were professional.

Of the five companies we contacted to take on the project, Econoloft proved to be the most professional during the initial stages from the first appointment, drawing up the plans, planning application, and ensuring everything was in place to start on the appointed day.The project was the conversion of a double hip gable roof which entailed the construction of a completely new roof. The construction, led by head joiner Sotir and his team, was completed in an impressive eight weeks and the quality of the workmanship from each trade, plasterer, plumber and electrician was first class. Always happy to go that extra mile Sotir ensured the smooth running of the construction with minimal inconvenience. A job of this size will always present unforeseen potential problems, but Sotir was always able to suggest solutions drawing on his considerable experience.We are very happy with the new space created and congratulate all involved on a well-managed and executed project. Thank you.

We got a dormer loft conversion (without en suite) to add an extra bedroom and make some other changes on the first floor (take out fireplace and create landing space). Econoloft were great from start to finish. The team at the office have been really quick to respond, the builders were very accommodating as we made a few changes during the build and we are really happy with the overall finish.
