Re: My Heating.
Hi
An update.
They are here, swapped the defective printed circuit board , which is outside in the heat pump in the garden.
It is raining, when they turned the heat pump back on it shorted out, water had got in.
They have now disappeared back to their depot, which is 30 miles away, to to make up a new part for the bit which has shorted out.
It is a good job that I have a sense of humour.
