Understand the heating system
Review heat load, flow temperatures, distribution and building fabric.
Heat pump & heating
Solar power becomes particularly valuable when it creates useful heat.
PHT coordinates the heat pump, hot water, thermal storage, solar PV and energy management.

What this solution delivers
Use solar windows
Heat hot water and thermal storage during PV production.
Protect comfort
Optimisation must not compromise hygiene, comfort or equipment life.
Clarify interfaces
Integrate SG Ready, Modbus, relays or approved APIs correctly.
Process
From the first photograph to a working installation.
Record heat demand
Assess consumption, system and temperature requirements.
Plan operating windows
Combine PV forecast, tariff and thermal storage.
Install hydraulics and controls
Connect sensors, storage, heat source and electrical control.
Tune the heating curve
Review data and fine-tune after commissioning.
Heat pump & heating
Combine electrical and thermal storage
A battery stores electricity
Flexible for many loads, but limited by capacity and investment.
A cylinder stores heat
Hot water and the building mass can absorb surplus economically, but only for thermal use.
Control coordinates both
Good priorities prevent batteries and heat pumps creating unnecessary peaks.

Frequently asked questions
Frequently asked questions
Can every heat pump respond to PV surplus?
Many have control contacts or interfaces, but the exact function and permissible operating limits must be checked for the model.
Is a larger hot-water cylinder always better?
No. Capacity, heat loss, hygiene, space and actual demand need to match.
Should the battery or heat pump have priority?
It depends on the season, heat demand, tariff, state of charge and objective. One fixed priority is rarely optimal.
Can an existing heating system be integrated?
Often yes, after checking hydraulics, controls and temperature levels.
