Daikin Altherma 3M ASHP and British Gas Hive Home
In August 2024, we went all electric had a new Daikin Daikin Altherma 3M Air Source Heat Pump fitted.
* Daikin Altherma 3M
* Daikin Low Temperature Monobloc 4kW Heat Pump (EDLA04E2V3)
* Daikin Indoor Unit
* Daikin WLAN Adaptor (BRP069A78)
* Daikin 150L Hot Water Tank
* Solar iBoost+
This replaced our previous Daikin Hybrid unit and we found that last Winter, the new all-electric system performed so much better than Gas/Electric.
However, during installation, our installers kept the existing British Gas Hive Home thermostat setup. Having learned a bit more about heat pumps since then, I've got a sinking feeling this may not be a good setup.
I'm wondering what the more experienced ASHP consumers think, and if this setup isn't optimal, what changes we should make -- either software tweaks, or hardware replacements/removals?
P.S. In case it is relevant, we also have:-
12 x 365W Solar Panels on our roof, connected to a Solax Power X1 Hybrid Series Inverter (3.0kW-7.5kW) and 2 x Solax Power Triple Power 5.8kW Lithium-ion Battery (50Ah), using the Octopus Energy Go tariff.

12 × 365 W solar panels (roof), 1 × 380 W, 1 × 400 W, 1 × 200 W, 2 × 100 W solar panels (garden)
We have a Daikin EDLA08 8kW monobloc (DHW is handled separately by a Sunamp Thermino ePC210 unit connected to our MyEnergi Eddi for grid / solar powering). We had the unit connected with the Daikin MMI and, for a few months, a NeoStat thermostat (on/off, bang bang nasty and unkind controller). I set the NeoStat some degrees higher than we ever needed and set up WC on the MMI. Once the Homely integration was made available, we had this fitted and since then, Homely has controlled the heat pump keeping us at 22.5 degrees C. 24/7. No regrets, it works well and we are comfortable all the time. Regards, Toodles.
