Old Potterton Promax removed today after a PCB failure, this was caused by the wrong Fuse being used at the spur, a short circuit on the old fan meant the boiler drew a huge spike in current from the mains power supply, instead of the 3A fuse blowing at the Spur, the PCB blew instead.
Rather than throwing money at the 16 year old boiler, we decided it was best for an upgrade, so in went the new Baxi 800 range!
The old boiler had a few things that needed altering to make it meet current standards, firstly the old condensate pipe was going out the wall and down into the external drain in 21.5mm overflow 😅 new 40mm pipe was installed to help avoid freezing and to meet regs. Then the new boiler was fitted with a Magnetic Filter as standard to help maintain the boilers already impressive 10 year warranty!
Final checks done and tested, hot water and central heating back up and running 🔥
