MCZ Musa Hydro 15kw - thoughts

The non-domestic RHI scheme (phase 1) has been running for some time. Phase 2 (domestic) is due to start in the spring but has been put back a number of times and there is a big backlog of installations to register. There is a lot of scepticism about it going ahead – there are rumours of an announcement at the beginning of March. How lucky are you feeling?

Each air to air heat pump costs around £1200 supplied and fitted so if you need two or three for the house the capital outlay is less than for a biomass boiler install. Running at 500% efficiency that's the lowest cost source of heat.

Rads may give even heat but how much energy do you think is wasted under floors, in the ceiling void and in heating up all the pipe runs?

You will need less kW of heat with air to air (because you won't be losing heat under the floorboards) and the unit cost per kilowatt hour will be 2.5p compared to 5p with pellets.

Your small profit on RHI incentive – how much have you factored in for annual servicing, replacement igniters and grates and other repairs? And what value do you put on your time fetching, carrying, stacking and loading bags of pellets? Can you put a financial value on your boiler being unserviceable and your installer saying he can't get round to look at it for two weeks because he's busy installing new systems?

We all make our own assessment of the risks and returns. A biomass system is a big outlay on complex technology and I would need to be very confident of high returns before committing. When I had installers quoting for my business none of them convinced me enough to trust them. They also proposed systems which made them the most profit at the expense of the profit I would have made from the RHI.

If you're determined to go ahead, good luck to you.

I am not going to bother applying for RHI, even if it comes about for domestic users, I don`t think it will happen btw. We have solar panels too, for hot water but energy outputs need to be metered so imo not worth it as our house is so energy efficient anyway and we would not be getting much

Having had a letter from MCS, re incidents of glass blowing out of Musa Hydro stoves, an engineer has visited and uncommissioned mine. I am without central heating in the North of Scotland in the winter (just great!!) and no idea how/when this will be resolved as it seems that blame is shifting between all parties. Is anyone else in the same boat? Any ideas what to do? I can't afford to run plug in electric heaters for long.... I think they are going to inspect all Musa Hydro stoves (?16,000 in the UK?!) so hoping there may be others out there who can help move things forward before we freeze!! Here's hoping

The problem is the installation of the flue.

(We have never installed a MCZ, but we have repaired/corrected bad installations)

I would recommend contacting whoever installed it, and get them to come and get it up to standard. And if that company has gone bust, spec flue should be able to recommend a company to come out and fix it

and now a list of mcs mcz suspensions

MCS has now been informed by BRE that the suspension for some of MCZ products has been lifted, with the exception of the following products below:



Suite Hydro 15 MCS BH0041/21
Club Hydro 15 MCS BH0041/22
Musa Hydro 15 MCS BH0041/23

Suite Hydro 22 MCS BH0041/24
Club Hydro 22 MCS BH0041/25
Musa Hydro 22 MCS BH0041/26


The products listed above are still suspended and cannot be registered on the MCS Installation Database until BRE inform MCS otherwise.

I rang specflue and have learnt nothing. They could not say anything except that mcz used to sell to anyone, even without the training. They will be talking with bre this afternoon and there should be some more info within the next two weeks

Our stove was installed by mcz approved installer, four years ago and was last serviced by a different approved installer as the first one went bust, so I am not too worried but I don`t like the uncertainty
