Underfloor heating in Victorian terraced house

[Anthony Crown]

Hi,

 

I am renovating my Victorian terraced house. We are going to replace the suspended floor at ground level with concrete, insulate and install warm water underfloor heating in it. We are going to add a loft and since that will be brand new underfloor heating is a no brainer, but for the existing first floor (which currently has hot water radiators)  I don't know what would be best, should I rip them out and install underfloor heating there too?   We are going to replace the existing floor so having to rip it out is not a complicating factor -- its going anyway.  Would I be wasting my money, or could it make sense?  (We are talking about 2 big bedrooms,   ca 500 square feet).

 

Cheers,

Makes sense to do it. What fuel are you using to run the "boiler/heat pump" If its a heat pump and you did want to stick with radiators you would have to replace them anyway and they are more expensive. A gas/oil boiler would be ok with existing radiators.

Mmm. How will the dpm tie into the wall?

Just run the DPM up the wall by 150mm.   Done this on many jobs inluding my own place which has a highish water table and no issues.

I am using a gas boiler, so I suspect that water temp for keeping the old radiators would not be an issue.

Are you living in the house during the refurbishment?

I don’t think my other half would be keen for me to rip up the first floor flooring to install UFH!

 

Ideal time to add some MHVR ducts to the ground floor ceiling at the same time!

I won't be living, we have to blast the entire stuff out,  turn the water off for weeks so that won't be a problem.
