Heat Pumps: anyone have one/thought about it?

I had an estimate from a local heat geek. Easy pass.

am i reading this wrong or are they fitting 2 x Vaillant Arotherm plus 12kw, as there is two listed

One is the heat pump, the other is ‘parts and fittings’ which will include everything from the heat pump controls to copper pipe. £4K seems quite high though but there isn’t a breakdown to look at.

The heat pump and cylinder price looks to be in line with one wholesaler I checked, it may be cheaper elsewhere though.

so parts and fittings dont come in the same box as the heat pump, really??? and an extra 5k nearly for those......

i would be exiting stage left with that quote

No, I edited my post above.

All that came with my Daikin is the unit itself. Even the controls are sold separately.

You have many meters of pipework, lagging, manual valves, buffer/volumiser, 3 port valve, pressure relief valve, anti freeze valves, cabling, electrical fittings etc.

There was a lot of kit delivered with my heat pump, probably not £4K worth though. They added about 30m of 28mm pipe alone in my install.

There's a lot of parts that are unique to each install, so not included in the "box", copper pipe, insulation, unions, fittings etc. It does seem high though, as does the labour at £550 a day, but is that one man for 10 days or 2 men for 10 days, depends how they are charging it out.

Will be interesting to see what mine comes back with.

Yes the actual pump and cylinder look alright.

But things like MCS registration and warranty, is that really £850? Handover and commissioning £300, err thats included in the £500 a day surely?

I am getting 2 more quotes from local places, another heat geek and the people who did my solar so will see what they come up with.
 
This was mine if it helps:

Description of goods and services Quantity Total
Goods
To supply and fit a Vaillant aroTHERM 5kw plus located at the rear of
the property in the agreed location below your bathroom window. This
will be mounted on the paving slabs which you will be laying – we will
require a level base for the heat pump to sit on with a suitable
soakaway installed to allow for the condensate to drain into – we have
not allowed for this in our quotation.
To supply and fit suitable strainer, anti-vibration feet & flexible straight
pipe kit.
To supply and fit Antifreeze valves to provide adequate frost protection
for the heat pump.
All external pipework on the heat pump will be lagged using Primary
pro insulation using bond and seal adhesive. This is protected against
water and UV damage to help limit heat loss from pipework.
To supply and fit a SensoCOMFORT wireless thermostat controller
complete with weather compensation sensor.

1 £3610

To supply and fit a Vaillant 200 litre heat pump unvented cylinder in
the loft, this will be fitted on a purpose made base which will be
designed to adequately support the weight of the cylinder, we have not
allowed for this in our quotation.
This cylinder comes complete with an expansion vessel & combination
valve.

1 £1295

We have allowed to run new heating flow & returns, hot, balanced cold
& mains cold from your current boiler location to the new cylinder
location. The cold mains will be routed from your incoming stop tap
directly to your cylinder which will allow us to have a balanced cold
feed to all outlets in your property.
We have allowed to run new flow & return pipework to your radiators
via a manifold setup – this allows us to run pre-insulated pipework
under your suspended floor directly to each radiator with no need for
fittings under the floor.
New hot & cold pipework will be ran to kitchen & bathroom positions,
we have not allowed to 1 st /2 nd fix any bathrooms or kitchens.
We have allowed to run primary pipework from your heat pump to your
cylinder location – this is likely to be inside the property and into the
loft via the bathroom wall.
A discharge pipe will be ran from your cylinder to a suitable position
outside via the bathroom.

1 £2280

System to be filled to VDI2035 standards to ensure minimal chance of
corrosion and bacterial growth in system.

1 £150

All associated pipework, valves, expansions vessels & fittings have
been allowed for.
Pipework will be lagged using 19mm wall insulation around cylinder
position in loft & 13mm under floors.

1 £2090

To supply and fit radiators designed to a 45 degree flow temperature
to the relevant rooms, these will be fitted with matching thermostatic
and lockshield radiator valves.
Main Bathroom – 900 x 800 K2
Bedroom 3 – 600 x 900 K2
Bedroom 2 – 600 x 800 K2
Bedroom 1 – 600 x 1400 K2
Hall – 600 x 800 P+

1 £1525


Services
Back office system design, set up and commission and handover of
new system, to include MCS compliance certification and BUS
application.

1 £400

Electrical Materials & Labour. Includes sign off and certification. We
have allowed to connect to a fuse spur & plug top in the cylinder
location for the heating controls which will be provided by your
electrician. An additional fuse spur will need to be fitted by the cylinder
location for a supply to the immersion heater.
We have allowed to run a cable from your consumer unit to the heat
pump location externally and to provide a suitable rotary isolator for
electrical isolation of the heat pump itself.
We will carry out all wiring of the central heating system.

1 £500

Labour 1 £4800
Sub-total £5700
GRAND TOTAL £16650
Total with BUS Voucher Applied
(£7500)
£9150
 
Geez that expensive.

I love the tech, but at these prices I feel it would be prudent to wait another 5 years or so.

Knowing my luck though as prices come down the grant will be gone or lowered meaning same price as now :cry:

My other worry is, what happens when it breaks outside of warranty? Sounds like a much more expensive bill then my plumber would charge.

My thinking is in the future more people will be trained in them in the next 5 to 10 years.

But yeah, very cool tech!

Same thing that happens when a boiler breaks I assume, repair or replace. Lets face it though most people cant afford these prices, cant see uptake getting to the numbers the govt wants.

The price isn’t coming down IMO, it’s only going to go up.

The only way to make it cheaper is to cut the installer margin on the job and given there is a massive shortage of installers, I can’t see that happening.

The likes of octopus are shaving off a few hundred in material costs but that’s it, the rest of it is from their margin/profit. No doubt there is also volume discount from the amount they also buy.

The heat pumps themselves al have been around for decades and are already produced in high volumes, it’s not new tech.

The benefit of a Monoblock heat pump is that you don’t need any certs to fit or maintain them.

In 15 years time, I could buy a replacement unit from city plumbing and install it if I wanted.

The only parts of the entire install you can’t do yourself is the cylinder and electrics which need building regs.

Is there really the three days work for an electrician???
No. Well it depends.

In principle you'll get a circuit for the heat pump, circuit for the immersion if you don’t have one already and any high voltage wiring needed for the controls.

Obviously every house is different in terms of complexity but I’d imagine most could knock that out in a day or two and a revisit for final connection and live.

This does worry me. Are heat pumps a fad? If the gov grants stop, then the uptake is going to be tiny as the cost will just be too high, meaning you'll likely be paying through the nose for a specialist in 10-20 years time as there's no tradesmen that want to touch them.

im guessing as you need MCS cert for the grant, you cant do any of it yourself??

Sorry - I meant in regard to what happens if it breaks in many years time and you need to replace it.

For a new install then yes you need an MCS installer if you want the grant.

Unlike a boiler where you need gas safe or a split heat pump (air con) unit where you need f-gas, as these are monoblock units you don’t need any certs to install them.

Well, it’ll be cheaper if there’s already a heat pump installed so you’re not having to make any changes to pipework or radiators, just replacing the heat pump or cylinder.

I think a lot of people are thinking a boiler costs £2k - £3k to replace but not factoring in property changes initially for a heat pump.

Gas boilers for new builds are going to be essentially banned due to the “future homes standard” and “minimum energy efficiency standard” that are coming along so I think that will be unlikely.

Labour have done a u-turn on banning gas boilers for existing homes though.
