Existing Hive with new Combi Boiler

[scottpetrie]

Hi
I had a gravity fed water with cylinder and heating system, which was run off my hive to operate both. I just had a new combi boiler installed so have done away with a lot of stuff. The sparky had a new hive ready but managed to use the existing one so the heating still works as normal on my existing schedule and app. The hot water on the app is just set to permanently off. Im just wondering, could I purchase a new hive thermostat and receiver to suit the combi boiler and would just be a straight swap, therefore removing the hot water side of things altogether?

Yes, but it wouldn't exactly be a straight swap.
To go from a dual channel Hive to a single channel Hive (Hive for Combi), you would move the wire from terminal 4 to terminal 3 on the receiver backplate, and then add a small link wire between L and terminal 1.
Very simple!

I will depend on the Combi boiler, likely no problem with an oil combi boiler, but most gas boiler can modulate. There are two ways to modulate the boiler, one return water temperature, the other is using the e-bus. Hive has no option to use e-bus.

There are likely to be far superior controls to Hive available for your new boiler which will make it more efficient. Do you know what make & model boiler you've had installed?

Hi
Its an Alpha E-Tec 33NX. Its all setup with the existing hive I had, just wired so its on the one channel. Was just a thought if I ever came across the single channel hive it would be better plus would remove the hot water setting from the app which I cant do. Maybe just my OCD kicking in!
