We recently acquired a new van for the fleet, this VW ID Buzz cargo.

Thank you to Vertu Volkswagen Hereford for supplying and Signs & Labels Hereford for the fantastic sign writing.

Another heat pump myth!

“Heat pumps are too noisy!”

Follow the link, you can’t even hear the heat pump over the volume of normal conversation

Heat pumps are running non stop, even while we film. For anyone who says they're too noisy or don't work: here's your answer. A warm home and lower bills, done right. Want a free home survey? Get in touch.

On a recent post we had a number of people tell us:
“ nothing wrong with glycol “

So here’s a little video from the heat geeks, who know their stuff when it comes to heat pumps, to explain it

Should I use glycol or anti-freeze valves in my heating system? Don...

Customer states:
- b**r is frothing at the pump.
- wastage is up to 50%
- the cellar fan is blowing but the temperature is 23°c.

What we did:
- on investigation the out door unit had corroded to the point the coil had developed a leak, left running the compressor has died.

- we replaced system with a Marstair cellar cooler

Cellar is now at the correct 12°c and wastage from frothing is zero.

Heat pumps don’t work 😳🫣😱

We hear this all the time, especially on fb.

Yet here we have a Samsung heat pump heating 250litres of water up to 50°c, at an efficiency of 362%.

Before the fb bandits get on

Legionella - is active between 25°c and 45°c, in stagnant water. This cylinder is replenished most days. It is heated to 50°c, above the range the bacteria like. It is heated to 55°c once a week and held there for an hour.

A twin split air conditioning system installed in a bungalow.

The living room unit will help keep the open plan living/dining/sun room cool in future heat waves.

The bedroom unit will help with a good nights sleep.

Both can heat 🔥 and cool ❄️ for year round comfort

Customer states the heat pump is expensive to run, on inspection of the system:

- system is filled with glycol
- lack of insulation on exterior pipes
- system runs at 50°c flow temperature whatever.
- radiator valves fully open.
- no filter on system
- tundish and pipework not to regs

What we did:
- removed glycol and flushed system
- installed anti freeze valves.
- installed a strainer
- insulated all exterior pipework
- removed and refitted tundish to regs.
- balanced the radiators
- set up the underfloor correctly
- set up weather compensation with a 40°c max flow temp @ -3°c.
- showed the customer how to adjust the weather compensation

Ready for installation this week

A busy week:
- remove old electric boiler
- change 8 radiators
- install new cylinder
- install 14kw heat pump

On its first run the heat pump showed a cop of 3.79 for the hot water, meaning for every kilowatt of electricity used it was producing 3.79 kw of heat for the hot water.

Over 3.5x more efficient than the electric boiler and with the cylinder in place the hot water is now at mains pressure.

If each kilowatt of electricity costs 25p, it’s only costing 6.9p per kilowatt of heated water

First time servicing a Trinaco Activair heat pump, solid units that operate quietly.
