is there any evidence of a DPM lapped up around the edges anywhere. - No nothing inside - I can see what I think is a DPM between some of the courses of brick from the outside of the property do you have air bricks - no which is partially I wanted to do something with the floor as it currently...

I guess that is my question. We are little limited as we do not have access to oil. When i say draughty its not like we have a hurricane flowing through, more it is quite a cold house despite having the usual insulation. We don't for example have condensation normally associated with this type...

@Notch7 silly question but is there any easy way or tell tale signs whether its a concrete slab or concrete oversite. The suspended floor isn't made using normal floor joists but rather 3x2 wooden floating frame then chipboard (200mm gap). The property site above the ground - has four course of...

Using an online retrofit UFH calculator looks like I may in be the region of £135-£185 sq mt. So for a 130sq meter property i'd be looking at £17550 - £24050 ouch! Ok might need to look at plan B - upgrading existing radiator sizes

@Mr Chibs for clarification, if the house already has a concrete base do you mean I would only need the top two layers? i.e. insulation 100-150mm and screed for UFH 75mm so total 175-225mm? hard core 100mm sand blinding 25-50mm concrete 100mm insulation 100-150mm screed for UFH 75mm

Thanks @cross thread I would actually like to remove the suspended floor as it has seen better days and is not ventilated. Trying to work out if 200mm is going to be enough space to install the UFH

Need to replace oil boiler and am looking at ASHP (no gas area). Have heard they are not very good in old houses unless you pair with UFH so was wondering whether it is viable to retrofit UFH into a 1970s house. House has concrete base with 200mm suspended timber floor where current radiator...

I imagine the concrete base would have a damp proof membrane in but perhaps adding another would be the way to go. I assume if I add a moisture barrier on top of the concrete base before the insulation, it wont cause an issue having two moisture barriers i.e. moistire wont get trapped between them

My thinking was removing the weird floating floor and taking it back to the concrete slab so i'd have plenty of room to play with. Then insulation, piping and screed

@Loofah I am ever the skeptic, and I know you shouldn't judge a book by the cover, but the first guy who came to the door looked less than professional. So much so, I phoned SCARF to see if they had heard of the company. They confirmed they had worked with them before, but I still will make sure...

@oldbutnotdead many thanks for the reply. Was tempted by the offer given my oil went from up £450 > £1350 per tank (3 required per annum), but the earache from the wife might offset the cost saving lol Plastic pipes are asking for trouble unless the cat steps up her game lol Will look into...

I am looking for advice about moving from Oil heating to an air source heat pump. I was contacted by a company to say that we quality for the latest government grant (ECo4 - Flex) to replace our 10 year old oil boiler. They are suggesting to move to an air source heat pump with solar PV system...

Got it now; sorry my brain was a little slow

Sorry, I am probably just being thick but what do you mean "cross-connect the WAN side port to the ONT with the other cable going back up to the switch"

OK, I think I understand what you mean now. Still confused as to the best approach lol
