Heat Only Boiler
10 Answers
Hi all,
I am looking at getting a new boiler and was wondering if a heat only one would be a better option for me as opposed to a combi? I have a 3.99kw solar panel system and all my showers are electric. washing machine is cold water fill.
Property is detached, double glazed, has cavity wall insulation and 750mm loft insulation.
I will have about a 12 - 14 radiators (I am planning to convert my garage in the future and would like to allow for this).

Not sure where to post so have posted also in How it Works.

We have fitted a few of the new Ideal Vogue boilers...

You can still have a combi and only use the hot water when needed.If you have a conventional boiler you will surely still need some hot water and so will need a hot water cylinder.The calculation for the radiators takes into account their size.On average 13 radiators would require around 35kW.
We have 15 and have a 52kW boiler.

My current system is over 20 years old and does not have a combi so everything is in place for a heat only bolier. My main concer was adding additional radiators to the system and wondered if an extra 2 - 3 radiators would be offset by the addition of double glazing, cavity & loft insulation. Given that boilers are now more efficient I was wondering what Kw I would require. My current boiler is an Ideal Mexico Super 2 but I can not see how many Kw it is. Is is more than sufficient for the current set up but I will be adding, in time, 2-3 more radiators.
Thank you for your help.
I presume that if I divied the Mexico Kw by the number of radiators I have (plus 1 to be on the safe side) and then multiple by the maximum number I intend having in the long run it should give me an approximate KW I need,
Have had 2 people come to quote so far one said 30-35Kw only other said 24Kw would be sufficient. I am awaiting prices from both.
One has suggested a combi and the other a combi or system boiler. Neither like the idea of a heat only but the one who said I could use a system boiler was on about not linking in to the hot water and putting in a new immersion heater.
All very confusing to me.

We have fitted a few of the new Ideal Vogue boilers...they are very good since Ideal had a good kick up the backside a few years ago.They have stainless steel heat exchangers which is a must have in my book.I would go for the 35kW with a feed to the DHW tank AND an immersion...you can use it during the day from your solar.
