40 + kw pellet boilers

lostinrates

Does any one have ( or install) pellet boilers of 40 kw or more? This is for large domestic use, and will eventually be part of an integrated system with solar thermal and pv units too.

Hi: go to HETAS and search for a biomass installer near you. More here.

Thanks. We have already met with one who has given us a horrific quote!

This made me want to ask here for anyone with experience of them, either fitting or just owning, for honest feedback while not in a sales situation.

Pop over to the pistonheads.com home & garden forum. There is a chap called RedLeicester who has one and raves about it...

Unfortunalely I don't know anyone personally with one. From what I have gleaned they are expensive to buy and not particularly cheap to fuel but can come into their own with very large houses where GSHP/ASHP is not practical and oil/LPG costs would be hideous.

Just saw your post here. If you google Baxi Multiheat you'll see that the 43 kW come in at almost £7000 plus ancillaries plus installation. Get 2 more quotes and compare like for like. Make sure the installer is MCS so you can take advantage of the RHI when (if?) it is available for domestic installations. Lots of discussion on the Green Building Forum and Navitron.

What you want to achieve will be v. pricey (speaking as someone directly involved in biomass, solar thermal, gas heating, plumbing and solid fuel...not into PV, oil, GSHP, or ASHP )

Thank you both!

This does really help.

We have no heating (there is a defunct oil boiler here,not repairable) so putting in heating is impotant to us, asap. Our house is old and not small. green would have been nice, self sufficient nicer but i am dubous aout the greenness of pellets and self sufficient seems not possible for our house.

I started saying that the one thing i did not want is pellet but all routes seem tolead back to it.

We really wanted ashp or gshp which w have been told are not suitable for here and woodpellet is. The tie of this is i will need someone to fill it for me regularly.

Hi: you can have a wood pellet boiler system where it is fed automatically via a hopper system...something like this.

Why do they say GSHP is not suitable? We have houses here running gshp units of up to 350 sq mtrs with normal radiators. Think your "advisors" do not know how these things work as have no knowledge, which seems normal in the UK..

Well, one potential builder is an mse-er and i know has done lots of research on my behalf over this, before that our architect (who has not worked with much gshp but was willing to and has the resources and knowledge to research new things very successfully, one of the reasons we instructed him was because of experience of this in a different situation) did lots of research. I believe it is felt that gshp may make an additional heating form, in the extension we build in the future (i know there was also some thought of looking in to both the shallow laying type and the deep columnar type) but it just was not seen as possible to be a reliable sole source in our old and never going to be sealed type house. Its a shame, because we have ample space to lay it. We also looked at water source heat pumps, but only briefly.

On a heat requirement analysis for this place it was deemed over and over again Unwise and not cost effective for the old part of the house.

Other things have had to give way too, i really wanted ufh instead of rads, but for similar reasons i am told it is just not going to be effective enough here. I don't know the square metrage here, but we also have high ceilings and 'issues' like chimneys and the original building materials (lathe and plaster walls, and listed buildings contraints. I certaonly know the big quote guy does gshp and did not recommend it for here.

The conclusive thing is cost and repayment time too, the incentives proposed for wood pellet are not to be sniffed at.

Edit..just trying to guesstimate square metrage we will at end of build and restoration be on the higher sq metreage, but also woth a greater house volume that one might expect with the high ceilings etc.

We have a hotel in the Scottish Highlands built in the 1860's, high ceilings, big windows and lots of outside walls.

It was heated by oil boilers until recently, mainly through cast iron radiators but with some more modern steel radiators too.

We experimented with different temperatures over the last few years and found that in our situation it was beneficial to have a lower temperature over a longer time period.

Our switch to GSHP, 2 x 37kW Dimplex 3 phase units, to cater for heating and hot water was completed earlier this year. We used boreholes in order to minimise disruption to our surroundings.

The system works really well and is as close to fit and forget as is possible.

We have been accepted onto the RHI and have had our first quarterly payment. Early indications are that the RHI payments will cover all of the electricity costs for running the system.

Happy to share our experiences with anyone interested.
