2 Port motorised Zone Valve Head 22mm Closed 230v Replacement for The Honeywell V4043H Compatible with underfloor Heating & Central Heating Systems

Great item, which arrived promptly. Item restored my Central Heating

Worked good water back hot

Fantastic 👍

Replaced a broken motorised valve, good value for money.

Arrived next day. Clear information and worked first time. Best to use a torx screwdriver

This is a direct replacement for a honeywell one & it fits & works as should. We have two of these headers...one controlling water to central heating & one for hot water.They basically let water bypass through or...shut water off....which of course is what you're setting through the timer controls.Our central heating stopped heating up yet our hot water was ok. I narrowed the problem down to this unit connected to the central heating pipe. I manually overridden the unit by sliding the lever on it...which effectively lets water pass through.....and I had hot water running through again. The problem was the motor in the old unit stopped working so the valve part (that this is screwed onto) was always in a closed position to stop water coming through the pipe. No working motor to open it (as timed). I'm not good at explaining things so hope this makes sense!Does the job....If your hot water stops coming through....try the lever on these units as a possible cause.

The product was as displayed and I was able to fit the product without any problem. I matched the product numbers as described . The product works well and does the job with my underfloor heating system. All is working well. The delivery was excellent well packaged and the arrival time was amazing. So far iam happy with the product.

Divert hot water on tank
