Air 2 water versus pellet boiler HELP!!

They are much more Eco compared to gas as they only use 1kw of electricity to every 3 kW of heat (basic analogy)

When you factor in the increase in zero or low carbon electricity being created through solar P.V and wind or even nuclear etc this makes it significantly less.

They would pay for themselves as I have said, it's just that it would take much longer than most people would accept if the RHI wasn't available.

A lot of the initial cost is due to a change in cylinder, change in heating pipe work, radiator sizing etc. the units themselves are reasonably priced. £10k sounds a bit steep mind.

Not sure what a tent has to do with it?

Temperamental that was meant to be
How long do you think the average heat pump will last without needing parts replaced
The compressor re gassed

There a hell of a lot more expensive to fit even on a new build when nothing needs changed

Let's say an average 200m2 new build
With underfloor heating at 150mm spacing 16mm pipe
I'd say total for materials
This would be with a oil boiler 300ltr unvented cylinder bundled oil tank
No labour just materials 10k to 15k depending on spec

Slightly cheaper with gas boiler

What would the price be roughly with a air to water heat pump

I've ripped out ground source and air source heat pumps because either
they cost a fortune to run
Breaking down
Or couldn't get house up to temp
As I've said before insulate and that is the best pay back you will get

 

[Nostrum]

Yep, absolutely right on the insulation. How often does your fridge or freezer need to be regassed? Never, unless it develops a leak. Other than that, there is a fan and some electronics, the same as anything now.

Air source could be installed for the same price as oil with tank and cylinder on a new build I would say. Ground source is a different story due to ground works and a slightly more complexed installation.

We fit Samsung heat pumps that include a 7 year warranty.

Like we've already said, the installs you've ripped out were probably installed or designed incorrectly.

 

[Gray0689]

Any air source I've ever seen priced is a hell of a lot more than an oil boiler and oil tank

If there so simple like a fridge/freezer why is there so many horror story's I guess I am very anti them as I've never seen a good one running well
Always cost way more in running costs than sold to the customer
And let's be honest if a fridge broke its normally just replaced
Not worth replacing compressor ect as a fridge is not that expensive
If your using the analogy of a fridge why are heat pumps so much more in cost

 

[Nostrum]

Supply and demand (hence the RHI)

Samsung probably make a million fridges a year as opposed to tens of thousand heat pumps (figures plucked out of the sky) so the cost per unit will be more expensive.

Also the compressor is bigger and it's generally a different unit in many respects but the technology is the same.

People seems to see heat pumps as some black magic or new fan-dangled technology when it's been around for years. heliotherm have been making heat pumps in Austria for over 20 years, if the technology was at fault then why are they still in business?

Most gas and oil boilers are oversized although the consequences are less disastrous. It's predicted that 60% of condensing boiler installed don't run as efficiently as they could due to installer error (or negligence)

There's more to heating design than hanging a boiler and piping it up as you most well know, but often that's what happens.

It's still a new technology to most people and anything renewable in this country will initially be expensive.
I agree most renewables now wouldn't be taken up without the rhi. Cheapest decent biomass boiler is £10000, £1000 for a good gas boiler,

£10k!?

I must have good terms!

 

[Gray0689]

You must be cheaper at fitting than any I have seen then

 

[Nostrum]

Maybe so mate, we don't charge Eco tax on it, just make it worth while with all the red tape involved!
