Underfloor heating is a great way to add warmth to your new London home extension without radiators using up valuable wall and floor space. But which type to choose for your project? At Simply Extend, we’ve put together a quick guide to what you need to know about underfloor heating.

There are two main types of underfloor heating system. The most common is wet underfloor heating. This uses your boiler to warm up water and then pumps heat through tubes installed under the floor – much like a standard gas central heating system, but without the need for radiators. Although more expensive to install, it is generally cheaper to run in the long term.

The other option is electric underfloor heating. This uses electricity to produce heat under your floor and, as such is more costly to run – although it is cheaper at the point of installation.

The main thing to note with any type of underfloor heating is that you should be careful with real wood flooring. If it’s not acclimatised to the heat then the wood may bow and warp. This is one of the reasons why tiles tend to be a popular choice in kitchen extensions when underfloor heating is being used. If, however, you do want the look of wooden flooring – try engineered wood as this will not warp and does not need time to acclimatise.

A typical home extension with underfloor heating

It’s probably not the first thing you think of when dreaming up your new home extension but once the cold snap kicks in, you’ll probably appreciate the heating option more than anything else.

So which heating options are available to you and which should you choose Simply Extend for your home extension?

In today’s blog we’re rounding up our favourite 5 Ways to Heat Your Home Extension in London and you’ll find something to suit any taste or budget on the list. Take a look through the options and decide which home heater is best for you.

Underfloor Heating

Underfloor heating is fast becoming the most popular solution for loft conversions since it allows home owners to maintain a clean and minimalist look for their new rooms; and also means they don’t suffer cold feet when they climb out of bed in the morning. Thanks to underfloor heating, you can choose any flooring solution from wood to tile or even slate without feeling the chill.


It’s not the most glamorous or aesthetically pleasing option on the list but radiators are a fixture in virtually every home in the country for a reason: they get the job done. They’re efficient and they’re cost effective. They just don’t add a lot to the aesthetic of the home extension. That’s where a more dramatic option works best.

Statement Radiator

Radiators don’t have to be stuffy and conventional. Choose the right one and it can complement the look of your new space. Statement radiators are a popular new heating option because they don’t just heat the room, they turn heads. They’re available in wide variety of styles and finishes. Unfortunately, you’ll pay more for the look than the functionality.

Towel Rail

Adding a downstairs bathroom to your home? Heated towel rails will ensure that your towels stay warm and dry. In the process, they’ll also heat the entirety of the room and make stepping out of the shower a lot more bearable in winter months. Towel rails are often considered an ideal second heating solution, to work in tandem with another, so probably not one for the tightest budgets.

Trench Heating

If your home extension features large windows, or patio doors, which could be responsible for letting heat out of the room, and letting cold air in, trench heating is a fantastic option. The heating system sits within the aforementioned trench and a grille filters the heat while complementing the aesthetic of the room. A variety of grilles are available and the cost of the system will depend upon your choice of materials.
