Running Cost Drivers: Tariff, Flow & Controls
The running cost of your bungalow's heat pump hinges on three main factors: your electricity tariff, the design flow temperature of your system, and your chosen control strategy. A lower flow temperature means the heat pump works less, using less electricity. This is a critical consideration for bungalows, where upgrading insulation might be necessary to achieve comfortable internal temperatures with a lower flow. Your tariff dictates the price per unit of electricity, especially important with flexible or time-of-use tariffs.
- Electricity tariff structure (peak/off-peak)
- System's design flow temperature
- Your chosen control strategy (thermostat settings)
