As mentioned on a previous post, I came across a YouTube video regarding a UK source of an electronic replacement for the mechanical pump for use with my 3kW diesel heater. I ordered one of these and have just installed it.
James Browning does not have a website. You send him an email to the address below and he sends you the details of his product. Note that you need to copy his address into your messaging app as the link below is an image not a URL. This affords him some protection against spam.
Installation of James’ box is straightforward with copious notes and videos to assist. Connections are simple – +12V, 0V and the two old wires originally going to the mechanical pump. You need to route the fuel feed via his box and then before running the heater you need to bleed the air from the pipework. There is a handy little switch in the box to help do this.
There is a knob on the box that alters the fuel mix which you can tweak with altitude. This is relevant if you are touring in a mobile home but not for my installation heating the workshop. The box as delivered has the fuel mix set to sea level operation and as I am at 90m asl I left it untouched.
So what have I noticed ?
First of all the old ticking noise has gone and the burner noise is more even. Major plus.
With the mechanical pump I had to put a metal plate against the wall to stop the soot staining the brickwork. Clearly the burn as it was was not correctly balanced to have caused this. With the new electronic pump all I have is condensation dribbling down the plate (it is freezing cold outside) so the burn is more efficient.
I can now burn our domestic heating oil (kero) as the fuel does not need to have any lubrication content as it did for the mechanical pump. Currently in the UK domestic heating oil is around GBP0.70 per litre and road diesel is GBP1.60 so a direct net saving amortising the cost of James’ unit.
Conclusion therefore : -no ticking, more efficient burn, lower cost fuel leading to an overall fast investment return and ultimately a net saving.
So far I am very pleased with the upgrade to my heater and I wish James every success with his innovation.
