Opinions for DHW

JohnnieK

Hi folks

I am going to be doing some work in my own house next year on the heating system. Moving the boiler up to the loft, what I'm at odds at is the domestic hot water situation. I was thinking of installing solar, I have a young family so it will be well utilized. Then my brain through a spanner in the works and I'm thinking of a combi boiler now. Seen as it's in the loft and close to the hot press and I have a lot of cold storage in the cistern I could put a Grundfos MQ onto it and pressurize the be Jesus out of it and have lovely showers.

I'm just looking for some opinions from people on this matter.:)

I have a combi in my own house and was thinking of doin exactly what you said ie. pumping it , the problem im having is as its fed from the mains at the moment if someone is in the shower and someone else is using the kitchen sink tap or d/s toilet which is mains fed the pressure in the shower drop significantly , so i was thinking of fitting a tank and pump in the garage where the boiler is .
The boiler i have is a gloworm 30 cxi , its crap , the plate to plate heat exchanger blocks up every 4 to 5 months , its a known problem with these boilers as im sure you prob know yourself , but other than that ive no other issues with the combi boiler , but would deffo go down the lines of a tank and pump installation , imo. its the only way to fit a combi boiler.

Thanks sullzz

I'm adding up the costs too. The combi set up would cost a lot less also compared to the solar. I will be doing up the bathrooms in the near future so might drop a gravity feed to the toilets then. For night time pee's

I think that sounds like a good idea. Pump through combi and have low pressure feeds to toilets if convenient.

Thanks Micky.

I'm getting consumed about this now. I refurbished a house last year were I fitted a similar set up and the customer swears by it. I was back last week to service the boiler and he really loves it. The mains froze for a day or two last year and he was delighted with the store of water.

That's the only way I will install a combi boiler as it does away with any issues of pressure fluctuation and as you said yourself if the water freeezes/goes off you have a decent amount of storage!!

That's the way I do them too. Just wondering which I should go for. System boiler with solar or the combi with the MQ.

Combi all the way. You won't get a more efficient system when you practically only heat the water you need at any given time.

Installation cost + running costs = winner.
