About iStore hot water
iStore Systems We Work On
Unlike the broader multi-category brands, iStore focuses specifically on heat pump hot water technology, which means the brand's engineering attention goes entirely into that one category rather than being spread across gas, electric and solar ranges. That focus often pairs well with solar power systems, since a heat pump's electricity use can be offset by rooftop solar generation during the day.
We install and service iStore systems with the same approach we bring to every heat pump job — correct siting for airflow, and an honest running-cost comparison against your current system before you commit.
New Heat Pump Installation
iStore heat pump systems correctly sited for airflow clearance and sized to household demand.
Compressor & Fan Repairs
Diagnosis and repair of the mechanical components specific to iStore heat pump units.
Control Board Diagnostics
Digital control faults and error codes diagnosed on iStore systems.
Electric-to-Heat-Pump Upgrades
Replacing an ageing standard electric system with an iStore heat pump for lower running costs.
Solar-Paired System Advice
Guidance on pairing an iStore heat pump with existing or planned rooftop solar power.
Noise & Clearance Assessment
Siting assessed properly for airflow performance and to manage operational noise.
Common questions
iStore Hot Water FAQs
iStore specialises specifically in heat pump hot water technology rather than offering it as one option within a broader multi-fuel range, which means the brand's product development is entirely focused on that category.
Yes — pairing a heat pump's electricity use with daytime solar generation is a popular combination, since it can further reduce the net running cost of heating your water.
Savings depend on your current system and household usage, but heat pumps typically use meaningfully less electricity than standard resistance element systems for the same hot water output. We can give you a realistic comparison based on your current setup.
It produces some operational noise similar to an air conditioning compressor — correct siting away from bedroom windows and boundaries matters for both noise and airflow performance.
Yes — compressor and fan diagnostics and repair is part of our regular heat pump work, and we'll give you a straight repair-versus-replace comparison based on the system's age.
