Wanting to retrofit UFH, so many questions.

[OnlyHumanHere]

Hi there,

So the title speaks for itself. I've just purchased a 1920s build 3 bedroom detached house.

Currently it has an immersion heater and no gas mains (the whole village is off the grid).

It has storage heaters at the moment but the wife and I are thinking about replacing them all with water UFH.

I'm looking at the prowarm system supplied by the underfloorheatingstore as they seem rather good and were very helpful on the phone.

Should I scrap the immersion heater and get an electri or LPG combi boiler? the LPG would need to be in bottles stored outside at the side of the house as we don't have a garden, only a little 3mx2m courtyard at the back of the house. Our kitchen oven/hob is currently connected to gas bottles on the side of the house.

If I keep the immersion heater, I was recommended by the website to get a ''slim jim'' electric boiler. If that a wise choice?

I was thinking of putting the 'slim jim' in the cupboard under the stairs with the main manifold for ufh...would i need another manifold for the 1st floor (only 2 bedrooms and a bathroom upstairs).

I originally made a post in the electricians forum, i tried copying it over here but it would let me.
For some reason I can't post URLs which is rather annoying as it means I can't post pictures or links to the products I'm mentioning.


Most the electricians were saying it wasn't worth it in a 1920s build since it'll be v expensive and a lot of work.

So first things first, just bought myself my first house First house, want to retrofit Underfloor Heating. 1920's build in Wiltshire. Should have the keys to it next week, can't wait

Floor plan

First problem is, no gas mains in the village. This means it currently has an immersion heater to supply hot water First house, want to retrofit Underfloor Heating. First house, want to retrofit Underfloor Heating. storage heaters for heat and the oven/hob connected to gas bottles stored outside on the side of the house.

So, after doing a bit of research and planning with my wife, we want to scrap the storage heaters, and go for water UFH with a free floating 8mm laminate flooring Something on the lines of this . Looking around, I think prowarm seem to do a good job with supplying all the parts we need, being bought from Theunderfloorheatingstore (regarded fairly highly online and seemed very helpful on the phone).

Now, my main concern is what to do with the heating element. I've spoken to a few specialists and I've been told either keep the immersion heater for the sink/bath water and get something like a 'Slim Jim'First house, want to retrofit Underfloor Heating. electric boiler for the UFH. Obviously the guy that recommended that was the website that sells it. However, again it's reviewed rather well and it'd be nice to keep all the product coming from one place.

Another plumber I spoke to recommended to scrap the immersion heater and get a combi boiler. He did say that if it was him, he would probably look at LPG combi boilers over an electric boiler for the long term cost saving (did a bit of research and yes, lpg is much cheaper than electric). However, when it comes to boilers, I'm completely lost as to what I need.


So my questions are...


* Keep the immersion tank or scrap it?
* Get an LPG combi boiler, electric combi boiler or just a stand along boiler for the UFH and keep the immersion tank.
* If I was to take the immersion tank out, should I put the new boiler in it's place? If so, would I need 1 or 2 UFH manifolds for each floor?

* I was thinking about putting the whole system (manifold and boiler) under the stairsFirst house, want to retrofit Underfloor Heating. would that make sense?
* Apart from the kitchen (which is tiled) and the reception (which is original parquet), the rest of the house is carpeted, is it relatively straight forward to just rip the carpet up, lay down the floating floor, insert piping, cover and just throw the laminate on top?
* One guy I spoke to said I would probably need to manifolds, 1 for each floor. Is that right?

* rippiing up the ParquetFirst house, want to retrofit Underfloor Heating and tiles in the kitchen, is there anything I should know before doing so?


I plan to try and get most the humping and dumping, laying the insulation for the piping, the piping and laminating myself, however I will be getting professional help for the installation and testing of the equipment.

Final Question, with multizone UFH...is the NEST thermostat (Gen 2) still a good option?

I hope I haven't made things too complicated.

What incoming electric supply do you have and how well insulated?

As I said, I've yet to be given the keys just yet so I'm just doing my research first to try and get a good amount of advice before I take the plunge with any big decisions.

the house feels well insulated, no draft...we visited the house a few weeks ago, the heating had been off for 3 weeks as the owner is in the Navy and seldom visits the house. It was freezing outside and the inside the house was just neutral, not freezing and not warm, so I'd like to think the house is well insulated especially since it had single glazed windows.

I've no idea what kind of electric supply it has.

What's the EPC rating and what improvements recommended

No mention in post #1 about not having keys. Well until you have the keys there's not a lot of point speculating about what could be fitted.
