Replacing Oil Boiler

[NewhouseOldhouse]

Hi

We are thinking of replacing our oil heating boiler.

Our house has an open fire back boiler and when we do some work we will have approx about 40 radiators to heat as well as water cylinder.

The system has a water storage tank in loft which feeds the water cylinder. The current boiler is probably 25 yrs + and it takes a long time to heat and just not efficient anymore.

What's the best boiler to look at for my setup? The current boiler is inside and if possible would like to keep it inside but a bit more quieter and pleasing to the eye as we are looking to have this room as a pantry of the kitchen.

Also, what would be a general ball park figure when doing this work?

Thanks for the advice.

Have a look at Hounsfield Boilers....very well respected on here.

People say about Grant Boilers how are these ones as well?

 

[Burnerman]

Generally well thought of, and a good choice.....it’s worth asking the local guys what they like though as they will know the back up and spares situation where you are.

Sadly I'm not sure even the biggest Hounsfield is going to be up to the job of running 40 radiators. Could maybe have two side by side if the OP has space?

@Breeno you really need to do a full heat loss calculation on your house to find out what power output your boiler needs to be capable of. Heat Engineer is a great one to use.

Assuming Hounsfield's biggest boiler (30kW) won't quite keep up, the next one to look at is the Navien LCB700 RS 36kW. I've fitted a few of these now, the technology is light years ahead of the likes of Grant, and you get a 10 year warranty. Really nice boilers and very competitively priced too.

If you want to use your back boiler as well then you may think of fitting a
neutraliser, and you may need to fit two boilers and an unvented tank or a heat store could be a path to go. Bob

I have not even seen a Navien on my travels.

Far better to fit one with an industry proven burner which has replacement parts available from stock in any town in the uk. Most of these parts are so widely used that they are essential Van stock to most service eng's.

Yup I think that’s a fair comment T. Bob

They've only been available for about a year, so it's not surprising you've not seen one if you're not fitting them. Still got some familiar parts on them - Danfoss pump & solenoids - and you don't need to worry about capacitors with them because there isn't one. Nozzles are standard Danfoss ones too. Nowt to be scared of
