New boiler advice - 4 bed multi-level Victorian house

[Mario123]

We are renovating our house completely and need advice on what type of boiler we should install. The boiler will be in the cellar, there will be a bathroom on the first floor and another in the loft room as well as a newly built toilet in the cellar.

We plan to remove the existing cylinder or is this a bad idea?
Are there systems where it's not necessary to have a water-tank?
We plan to have underfloor heating throughout the house including the first and top floor or is this a bad idea? We wanted to remove all radiators but some people telling us underfloor heating upstairs is not a good idea.

Thanks for any advice, we really appreciate your help.

Cylinder in the centre of the house may be the best option, hot water will get to taps quicker, if you had a combi it would take a long time to get to te taps.

A 4 bedroom Victorian house will NOT NEED
1. A combi boiler of any size type or specification - so that means you will need to make space
for a mass hot water storage device.
A 4 bedroom Victorian house WILL NEED
1. A properly sized system boiler
2. Radiators on the upper floors
3. This will feed you no rad grd floor system
4. Mains pressure 'megaflow' hot water system maybe with
5. More than 1 x coil to take advantage of solar thermal heat

If your local ie 100 miles from L37 I could come and have a look

Good thinking CHK

Depends on water pressure, if low pressure a megaflow wouldn't work

 

[SafeGasInstall]

it will with a break tank and a booster pump

OP it all depends of your water supply and what you are looking to have done really !

list your location and a member from here could help you to make this really important decision of what to have installed to keep you happy for the next 15 years

It easy as below fit a break tank booster - added the price of a proper set up as the enquirer is looking at
its buttons and there is a really good set up which will last 4 many years -

might even outlast Croppie ! If he still STOPS having a beer or 2 - BEER IS GOOD

More things to go wrong, I would just fit tanks high up in loft and a cylinder.

 

[eaton]

Could fit accumulator as other option.

Acumilatie is only for the times of the day when you don't have a good flow but you have a good pressure !

 

[eaton]

You've obviously never fitted one with a comment like that! Just make sure the accumulator is bigger than the cylinder and they work perfectly.

Here we go ........who is to read manufacture instructions

and how is a going to boos your pressure a ???

 

[SafeGasInstall]

You sound like a mate who's name is Simon who done just as you said and was going to court as the system fail to deliver hot water . Boiler cylinder all in basement income pressure 2bar flow of about 17l ......
Barhroom on the 4th floor never got any water ......
So I realise Dickies was right early on .......

I completely agree, low pressure and it won't work properly,

 

[SafeGasInstall]

I am not web going to read all be said about the ASHP as if he fail on a water not much to impress me on the renewable !

 

[eaton]

I'd love to answer but I'm struggling to read half these replies! English is a disgrace on this post

 

[hammers4spanner]

stan's not english

 

[SafeGasInstall]

Sran it's not a English man that is true , an most of the time he uses his iPhone , and then he never checks the spellings !
I do apologise for that post it's really bad , I know !
All I wanted to say is that accumulator suggestion was not a good idea as there is no way accumulator will increase the mains pressure !

 

[eaton]

It won't increase it no but it will provide adequate pressure to satisfy a unvented.

 

[tamz]

More flow but it can only provide the same pressure as it gets put into it.

 

[stevetheplumber]

agree with stan if theres not enough pressure in coming an acumalator wont help
