Selection process
Sized around storage, recovery and daily demand.
The right system depends on daily draw-off, storage capacity, installation location and recovery expectations.
- 01
Estimate hot water usage
Review household size, bathrooms, fixtures and peak usage patterns.
- 02
Select storage capacity
Match tank volume and recovery to the household demand.
- 03
Check location
Confirm airflow, access, noise, drainage and plumbing constraints.
- 04
Coordinate installation
Plan plumbing, electrical connection, condensate and commissioning requirements.
Technical planning
Storage and recovery determine the right hot water solution.
Domestic hot water heat pump performance depends on demand, storage, climate and installation conditions.
- Occupancy
- More occupants and more bathrooms usually increase storage and recovery requirements.
- Storage tank
- Tank volume should match daily draw-off and peak hot water demand.
- Airflow
- Outdoor or ventilated locations need enough airflow for the heat pump to operate correctly.
- Noise and access
- Unit location should consider acoustic impact, service access and plumbing routes.
Suitable projects
Where domestic hot water heat pumps fit.
- Homes replacing electric storage hot water
- Homes moving away from gas hot water
- New all-electric dwellings
- Renovations with hot water upgrades
- Projects comparing Sanden and Stiebel Eltron options
- Households with predictable daily hot water demand
FAQ
Common domestic hot water heat pumps questions.
What is a domestic hot water heat pump?
It is a hot water system that uses heat pump technology to heat stored water more efficiently than direct electric resistance heating under suitable conditions.
What affects the system size?
Household occupancy, daily hot water usage, storage volume, recovery time, climate and available installation space all matter.
Can it replace gas hot water?
In many projects it can be considered as part of a move away from gas, but site constraints and household demand should be reviewed first.
Which brands does SmartHeat reference?
