Heating System

vanman99

Hi, putting the internal plan together on a self build, looking for recommendations on the best or most effective or efficient heating systems? will be putting a large stove linked to back boiler in the main room, outside of that will have standard rads, but what's the best method for heating those, would love to get a way from an oil boiler, wood chips seem to be linked to the price of oil so not sure i'd want one of this either. what do people recommend? 2000sqft dormer.

Depends on what you want to spend and are there any space constraints etc.

An attractive option is a Stove linked to buffer/accumulator tank, paired with either oil boiler - gas boiler - or alternative fuel.

A new efficient oil boiler linked to a buffer/accumlator tank would be an efficient setup assuming its all designed and commissioned correctly, as you would ensure there would be no short cycling of the oil boiler.

The best advice you can give people is to be look at increasing your insulation and airtightness first when you have that fully planned and thought out, then you are in a position to know the heat demands of the house start planning that system.

Thanks Outkast_IRE, yes we requested upping the insulation and is now added to the spec plus there is specification in the quote for air tightness which i'm happy with. I'm budgeting around €5k for a decent system but that's with a small amount of research so far.

Firstly, you are proposing a self build, which trigger a few queries in m mind:
1. Has the proposed development received planning permission?
2. "Self build", does this mean you propose to use direct labour?
3a. Is this a whole new house, or a extension and renovation project?
3b. If it is an extension, what is the floor area of the extension?
4. What does the DEAP (energy assessment for the dwelling) advise with regard to the proposed heating provision?

Thank you.

Hi Bubbling -

1. Yep, Full Planning
2. Not direct labour, under contract but i need to decide on the system
3a. New House
3b. N/A
4. DEAP - ?

You need to get a BER assessor to look it over, They do calculations based on the conditions and can make recommendations to the overall efficiency and what types of systems to go for.

DEAP = have a look on SEAI website - search for DEAP. (I can't post the link for some reason)

This is a requirement for building new dwellings under the Building Regulations (Part L).

Who designed your house and compiled the planning application? An Architect? An Engineer? A Draftsman?

You need to speak to a Professional (not a guy drawing a 'cheap set of plans') about doing a comprehensive detailed design (including carrying out DEAP) that can be tendered by Builders. The better prepared the tender documents are, the less headaches there should be on site. Additionally, it should mean that the house will comply with the Planning Regulations, the Building Regulations and Building Control Regulations. Remember, this is the biggest investment most people make in their lives - the better designed, detailed and built the house is, the more value you will obtain from it over its / your lifetime.

It is worrying that you have not been informed about DEAP at this stage in the design process!

Are you aware of the Building Control Amendment Regulations and the huge effect they have on building and compliance?
