Thanks guy's. is 20m away excessive or quite common? A depth of 450mm should suffice too hopefully

Gasguru is completely right... 80% of boilers installed nowadays are combi's (no doubt someone will say 79% or something silly!) Anyway, most of them serve small flats with 3 or 4 rads with an output requirement of nowhere near 9kW and they work fine. Just put in a small combi.... do not lose...

Can anyone offer some advice please, If the plant room to a large house is in an outbuilding away from the main property to be heated about 20m away can the heating F&R's and the cold, HW flow & HW retun be run underground with insulated pipework. If so has anyone got any recommendation on the...

Hi Tony Is the proposed boiler not going to be a combi though? Although I see what you mean, even the system boiler will have the same size integral pump. When you say balancing valve, do you mean the valve before the cylinder to balance the heating and HW input?

Sound like a large property, how many bathrooms is in the house.... sounds a bit big for a combi boiler on the HW side??

Then why would there be an option on their application form to have it internal??

This rad is acting as a reference radiator for the operation of the room stat... it is probably acting as the by-pass for the system too

... i think i would rather be on the dole!! :lol:

Small wood pellet / chip / log boiler?? Just top it up yourself and connect to existing system... no oil or lpg required... go green and save money plus puts more on house when you sell it in a few years. Cost will be much less than oil and lpg... although most on here would try and talk...

Thats a yes then i take it?? Because if british gas won't then e-on will! :lol:

I think the 'above ground entry' means to an internal meter, there are options to have a bolt-on or built in meter too.

Can gas meters to new houses be positioned internally? I know National Grid have an option on theire 'new connection' form to choose an 'above ground entry' so I assune this means if you want the meter inside?? Cheers guys :lol:

I agree, but maybe go to at least a 250 litre (150 is abit small for 3 baths?). Combi will be useless in this situation...

Thanks Dave, It is Uponor's system which runs off a low voltage and has a pulse sequence to the dial type stats. I was thinking about putting it outside the room near the doorway, but I kinda think it will defeat the object slightly as that area will be in the corridor / bedroom which already...

Yes, I understand how u/f heating works! I don't think its nonsense. What would you recommend then? The cost is neither here or there for the bathroom uf heating. The bathroom is quite large 14 sq. m, surely there should be some form of control in there. I don't want to go for the easy way as...

There is going to be underfloor heating throughout the property with individual thermostats in each zone. I assume therefore the heating for the other areas will be controlled via their respective stats not the stats in the bathrooms as they will only be controlling the circuit in that...

Why? Just spoke to a manufacturer who said they can go in as long as they are within the required 'zone'

Just some advice please, I'm installing underfloor heating throughout in my property, can you put room thermostats in the bathroom and en-suites?

Have you tried seeing how much a gas connection would be... I assume there is no gas nearby?? Why don't you look at a small wood chip boiler or even wood pellets and go the whole way... they are fully automatic and of course doesnt need oil.

This is quite a strange request by NG as I have seen their application forms and there is quite clearly an option to have an 'internal meter' fitted inside the property. I do know it is easier for them to install outside so they tend to push this option onto you. Also it is easier for them to...
