warmflow cabinpak with an unvented cly.the cly cannot be connected directly to the mains so you will need a break tank and booster set,or have a well bored and supply it from there.avoid a combi at best you will get 18l per min at ONE POINT AT A TIME five beds means more than one bathroom so that rules a combi out.have a look at pellet burners grants are good in ireland.

right ok,leave the combi then

but with the pellet boilers you need abig space to store the pellets
anyother you can think of?
 
firebird/grant/worc/turco plus a whole lot of others,choice is yours but i would stick a warmflow in as they are reasonably priced and still work after thirty years of neglect,avoid a condenser if you can absolute ruuubbish and hardly condense so the savings are minimal.insulate insulate and insulate again is the best way to save money.as you are in the west it will need good controls as it gets a bit blowy over there.trvs/room stats/good pipe insulation not the cheap 9mm rubbish that the majority use,19mm armaflex even 25mm i know its expensive but the payback is realistic.

I would recommend you stay loyal to your country and fit a Grant ;)
 
all they seem to have out here is the firebird,any good?
 
dont know really?
is under floor heating better
 
Miles better IMHO.
If you ever opt for a ground source heat pump system then the unit could run at night time using cheaper electricity and the heat in the screed will be stored and released through out the day.
The same with solid fuel. The new biomass wood boilers run at their most efficient at full tilt. That means huge and expensive thermal stores are needed to store excess energy. With high mass UF heating the screed is the store so the thermal store can be down sized or eliminated altogether.
You have the choice between a cheap oil boiler and expensive fuel oil or expensive biomass or heat pump appliance's which are grant aided and slightly cheaper fuel.

I would be considering a 150mm cavity on a new build, pumped with bonded bead. The cavity ties for this size are becoming more popular. A few people have built 200mm cavities but sourcing the ties might be a problem. Underfloor heating through out. Concrete span decking if its two storey and a Grant multipass 40 kw condensing boiler coupled with a decent controller.
Well Im doing a bit of work on a 5 bedder at the moment over in the east of Ireland and thats what's going in with the option of adding a huge wood burner later of some kind.
:D

Also your painter will really like you. :D
And you won't have the bother of sludged up radiators in a few years time and unsightly great hulks of rusting steel in about 15 years time hanging off your walls taking up valuable space and spewing black water out of leaks at the seams. :(

,avoid a condenser if you can absolute ruuubbish and hardly condense so the savings are minimal.

Unfortunately, Building Regulations require a condensing boiler to be fitted, so if you go with an oil fired boiler (Grant Vortex's are good) then it will have to be condensing... although I do agree with numpty1... then are not often in condense mode.

If you go with a pellet boiler you need to ensure you have enough room for a pellet store... unless you have a small hopper on the side of the boiler, in which case youwill need to be prepared to manually fill the hopper every few days. IMPORTANT: check on wood pellet suppliers and security of supply before you go down that road. Also look at how much they are per. tonne... it will be cheaper than oil but you need to look at payback.

Install u/f heating throughout and make sure you have enough hot water storage and water pressure before rushing into things. Combi....???? NO NO NO, it will never cope with the demand on a 5 bedder!!
 
I didn't think the rules on condensing boilers had come in yet in Ireland :confused:
