Thank you for buying a Samsung EHS heat pump system, your Samsung heat
pump heats the house and hot water cylinder much like a normal fossil fuel
boiler however there are a couple of differences which you should take notice
of.
Your installer should have provided you with a room thermostat if you have radiators
or a thermostat in every room if you have under floor heating.
To turn on the heating all you need to do is turn up the thermostat, to turn it off you
need to turn all the stats down. The thermostat sends a run signal to the heat pump.
Once the unit starts up it will take time to get to temperature, it is not instant. Within
10 minutes you should feel the radiators beginning to warm up.
Weather compensation and water law:
The radiator temperatures will be lower than you are used to with a gas or oil boiler.
To add to this, we run them in a weather compensation mode, this means that the
unit measures the outside temperature and adjusts the radiator temperature to suit.
The colder it is outside the warmer the rads will be and vice versa. This function is
automatic and is designed to save you money. In very cold weather the radiator will
be at their hottest, they will reach 50C.
Once the temperature outside gets cold your heat pump will stop and it will fire the
boiler, this will make the radiators much hotter in cold weather.
Running your machine efficiently
It is very expensive to heat the house up from cold, with a heat pump the best advice
is to maintain the house at as close to constant temperature as possible all the time.
Please DON'T set the room temperature too low when you leave the house, ideally
drop it 2 degrees below your normal set temperature when you go out or it will take a
long time and a lot of money to recover.
To switch off the heating in summer set the thermostats down to 16C to avoid the
heating starting up.
Your radiators will have thermostatic valves on them, you can adjust each room's
temperature with these.
