Building advice: Can underfloor heating be installed as part of renovation of existing house?

Expert builder Kieran McCarthy answers your queries

Underfloor heating is a very even heat source.

Hi Kieran. I have a few questions about underfloor heating. What are the different types. Can you install it in an existing house? What are the other types of central heating available? Finbarr O'Riordan, Macroom 

Thanks Finbarr. So as we are still making our way through the tail end of winter we are likely still using our heating systems at full throttle. If, like me, you live in an old house, you likely have a gas or oil-fired system and radiators. You arrive home in the evening (from your 5km walk!) and the house may be freezing so you crank on the central heating at full tilt. In truth, if this is the case, you may indeed have a poorly designed central heating set-up. What is more efficient and creates a more consistent living environment is a thermostatically controlled underfloor heating system.
