Passive heating system for a new build

jose66lorenzo

Hi All,

I am currently building a 2200 sq ft(204m2) dormer bungalow. i intend to insulate the life out of it aswell as get the house air tight. I intend to install a HRV system with boost functions in each wet room. The heating system i hope to use is a 14kw air to water heat pump with ufh.

As a back up i also intend to 100% air sealed stove with a back bolier for exceptional cold spells. I also hope to have solar tubes to warm the water.

I intend to have a well insulated buffer tank which will be fed from solar tubes, back boiler and HP going to under floor heating and the upstairs rad.

My questions are:

What size buffer tank should i have?
Should i use Dimplex smart rads( which are noisy but economical) or double panelled steel rads (which will reduce the buffer size needed)?
Can anyone recommend people in kildare or near which will make the house air tight, supply & install air to water pump, buffer tanks and ufh.

Also can anyone recommend places to get an airtight stove?

Hold your horses with that beast of a heat pump, 6 to 7 kw ground source and 10kw air source maybe a bit less depending on just how much insulation you use,
Dimplex rads if you absolutely can't underfloor it
Your going to some serious overkill and expense on the heating system with solar, back boiler and buffer, with all your going to spend you'd get a borehole and heatpump and you'll never need a backup,
Talk to a good heat pump supplier first before you spend a fortune
