Premier Heat to Amptec: which model replaces which
| Premier Heat model (discontinued) | Amptec for radiators | Amptec for underfloor heating |
|---|---|---|
| PH4kW (4kW) | Amptec C400 | Amptec U401 |
| PH6kW (6kW) | Amptec C600 | Amptec U601 |
| PH9kW (9kW) | Amptec C900 | Amptec U901 |
| PH11kW (11kW) | Amptec C1100 | Amptec U1101 |
| PH12kW (12kW) | Amptec C1200 | Amptec U1201 |
What the Premier Heat was
The Premier Heat was a slim, wall-mounted electric flow boiler for wet central heating in homes with no gas supply, or where a flue was not possible. It worked with standard radiators, programmers, central heating pumps and room thermostats. The Amptec range does the same, so an Amptec can usually go in where a Premier Heat was planned, using the same pipework and controls.
Choosing the right Amptec size
Amptec models starting with C are built for central heating with radiators. Models starting with U are built for underfloor heating. Make sure you choose the right letter for your system.
As a rule of thumb, allow about 1kW of output per radiator, or about 100 watts per square metre of underfloor heating. For example, the U901 covers up to 90 square metres of underfloor heating. If you need more than one boiler's output, Amptec relay kits (RL1, RL2 and RL3) let you link boilers together. Call us and we will tell you which kit suits your setup.
Hot water
A flow boiler heats your radiators or underfloor circuit only. For hot water you will also need an indirect hot water cylinder, such as a Heatrae Sadia Megaflo.
Running costs
Electricity usually costs more per unit than gas, so an electric flow boiler can cost more to run. Running costs come down on an off-peak tariff such as Economy 7, and an electric boiler produces no emissions where it is installed.
