Tony the Op has told you it is a man cave, he is not moving in a family of Saree wearing refugees , he needs some heat while watching the footie and the occasional shower, so the wife didnt know that he was on Porn hub at half time, a U6 will be fine as long as all the pipework sizes are correct, you have had two nights to google Diversity factor so what are your calculations ?But a much more capital cost effective solution would be an electrically heated cylinder and electric space heating, possible electric UFH.
It all depends on the amount of usage it is likely to get.
Most I see are little used after the first burst of enthusiasm.
To fit a reasonable combi and three rads I would be charging about £2400 and that is without the 25 m of gas supply pipe from the house!
@Agile care to comment on the ops existing electric setup and what requirements you think this all new electric heating setup might need plus the effect on the existing cutout, tails, consumer unit?.
But it is a man cave who is going to light it and clean it out ?????He is going to lay the steel armour in the trench foe the gas pipe!
The electrical supply will be out in by pixies,free of charge of course ,funny you don't see that happening in most of the places around here
If it's going to be a man cave I woukd.look at wood burner myself,there is something beautiful about a real fire
But it is a man cave who is going to light it and clean it out ?????
