Technology planning, not a fixed-price offer

Combining Solar and Heat Pumps

Solar generates electricity; a heat pump uses electricity to move heat. Their seasonal performance and operating schedules need to be assessed together. Agua-Therm is the primary heating specialist; LIT handles the solar work.

Agua-Therm

What to specify

Solar generation

Check seasonal rather than annual generation alone
Allow for shading and daytime export
Coordinate the solar scope with LIT

Heat-pump design

Calculate heat loss and hot-water demand
Check emitters and required flow temperatures
Assess noise, siting and electrical capacity

Controls and operation

Plan hot-water and heating schedules
Check compatibility with existing controls
Review pool heating as a separate load

Build the plan before comparing prices

Have Agua-Therm assess heating demand and the existing distribution system.
Ask LIT to compare seasonal solar generation against the proposed electrical load.
Agree each division's scope, interfaces, controls and aftercare responsibilities before work starts.
