Project Overview
Dependable Hot Water, Far Less Energy.
An ageing cylinder was slow to recover and expensive to run. Gullwick removed it and installed a high-efficiency unit sized to the household’s actual demand.

An Old Unit Was Costing More Every Year.
The existing heater struggled to keep up with morning demand and was running well below its rated efficiency.
The Challenge
- Hot water running out each morning
- Long recovery time between uses
- Energy costs rising year on year
- Unit well past its service life
“Booked on the Monday, fitted on the Wednesday. The difference in how quickly the hot water comes through is obvious.”
Correctly Sized, Correctly Installed.
We calculated the household demand, removed the old cylinder, and installed and commissioned the new unit in a single visit.
The Solution
- Sized the unit to real household demand
- Removed and disposed of the old cylinder
- Installed the new unit and safety controls
- Commissioned and set the flow temperature
The Result
Hot water is now available on demand throughout the day, with a clear drop in the household’s energy use.
