Underfloor Heating Installation in Kingston upon Thames: Frequently Asked Questions
Wet or electric underfloor heating — which is better?
Wet (hydronic) systems have lower running costs and are ideal for whole-house installations or new builds. Electric mat systems are cheaper to install, thinner (less floor buildup), and better suited to single rooms like bathrooms or kitchens as a retrofit.
Can underfloor heating be installed on an existing floor?
Yes. Electric mat systems add only 3-5mm to floor height. Wet systems can be retrofitted using low-profile panels that add 15-25mm. However, the most cost-effective time to install is during a renovation when floors are being replaced.
How much does underfloor heating cost to run?
Wet underfloor heating typically costs 15-25% less to run than radiators because it operates at a lower water temperature (35-45°C vs 65-75°C). Electric systems cost more to run but are usually only used in individual rooms.
Getting the right price for a underfloor heating installation in Kingston upon Thames is straightforward when you know what to expect. The best approach is to get at least 3 quotes from vetted local tradespeople in Greater London before committing to any work.
