Comms and power cabling to outside unit

Papahuhu · 2026-07-16T17:44:05Z

Does anyone know if 1. The comms cable should be 50 mm from the power cable (mine isn’t, it’s been clipped to the power cable). The install manual says it should. 2. Is it mandatory (MCS or electrical safety regs) for the power cable to be run inside trunking. Mine has just been clipped and runs on the outside of the brickwork. The reason I ask is that the install manual states it should be run in ducting of suitable IP rating to protect from water and possible shock. I just had a service from BG and they indicated it was a problem/contrary to install manual. I approached the installer and they said it was not an issue. Thanks

I can only guess the issue is with cost of disposal or refilling. I know they also limit it to certain manufacturers too, I assume to the ones that BG fit themselves.
The pricing is a bit weird, it works out about £5 a month extra for break down cover above and beyond the service cost, for parts and labour I thought that was cheap as chips.
But the same cover for non warrantied systems is nearly £600 a year and has limits on part costs.

Yes, but that break down cover specifically excludes repair or replacement of your heat pump or controls, so only really includes your pipework and radiators (pumps, valves etc not within the heat pump box) that any plumber could repair, hence the low additional cost. Anything else would presumably be bounced back to the OEM for a warranty claim.

Samsung 12kW gen6 ASHP with 50L volumiser and all new large radiators. 7.2kWp solar (south facing), Tesla PW3 (13.5kW)
Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.

100%, the cover is for warrantied units only. How it works in practice is that in the event you wake up to no heating or DHW, call BG and they assign an engineer to diagnose fault. If the fault is outside of of ASHP or controls, they fix directly. If it is heat pump or controls, they liaise directly with, in our case, Samsung, and decide between them whom does the repair work. What I was told is that in the case of simple repairs, BG does it, for complex faults BG Samsung assign one of their specialist engineers.

(hope you are getting on well with flux, for me it’s been it’s worth nearly £100 a month on top of outgoing?)
