Does a combi boiler have 2 heat exchangers?
The combi boiler has two heat exchangers, with the primary heat exchanger handling water for central heating while the secondary heat exchanger deals with hot water through the tap. The pipework and water for these are kept completely separate.
Can I use any wireless thermostat with my boiler?
Can you connect a wireless thermostat to any boiler? The particular wireless thermostat you have will affect whether it can be connected to your boiler. In most cases, they are compatible with most modern boilers, including combi, system and heat-only boilers.
How does multi zone heating work?
Multi zone heating allows individual rooms or zones to be heated to a specific temperature, at a specific time of day. This is usually achieved through the use of smart thermostatic radiator valves and it means you don’t waste energy or money heating rooms that no-one’s using.
Can my boiler handle another radiator?
Putting in one or two extra radiators will probably be fine, though you should always check the capacity of your boiler in the manufacturer’s manual before proceeding. If you wanted multiple extra radiators, it’s very likely you’ll need to upgrade your boiler as well.
What does a secondary heat exchanger do in a boiler?
As hot waste gases were produced, the water that returned from its circuit around the radiators was pushed into the secondary heat exchanger, which only used waste gas to heat the water. Once it had been heated slightly in this heat exchanger, it returned to the primary one to become even hotter.
What does a secondary heat exchanger do?
The secondary heat exchanger is where the flue gas undergoes further heat exchange and water vapor forms. After exiting the primary heat exchanger, the burning gas proceeds to the secondary heat exchanger. As water is changed from a vapor to a liquid, it releases more heat into the secondary heat exchanger.
How do I connect my wireless thermostat to my ideal boiler?
Hold the thermostat approx 2 metres away from boiler. Locate the gateway adjacent to the house wireless router and connect the supplied ethernet cable from the gateway to the wireless router as shown. Connect the Gateway power cable and 3 pin plug together, then connect the 3 pin plug to a convenient mains socket.
Will any wireless thermostat work with any receiver?
Any wireless programmable thermostat will work with the existing receiver.
How do I install a wireless boiler thermostat?
Quote from the video:
Quote from Youtube video: Each zone has a zone valve. They're connected by wires between the zone valve and the thermostats upstairs when the thermostat sends a signal.
How many radiators can you run off a boiler?
How Many Radiators Can a 30kW Boiler Run? For combi boilers, sizes from 28 to 32kW can keep between 10 and 15 radiators nice and toasty. On the other hand, 30kW heat only and system boilers can heat 15 to 20 radiators, making them the ideal choice for running larger properties.
Can you daisy chain radiators?
Connecting your radiators using a one-pipe system
Radiators connected by way of a one-pipe system operate in accordance with the principle of a daisy chain. This means the return water of one radiator serves as the supply water of the next radiator unit.
Can you connect two radiators together?
Radiators (generally) are plumbed in a parallel circuit in order for them to work correctly. If you join them in a line (serial connection) then one radiator will be hotter than the other, and the flow through both radiators will be limited to wherever the greatest restriction is.
Can one radiator feed another?
If you want to add in a radiator to your central heating system, it’s easy enough to do. You can add a radiator at any point in the flow and return circuit, but you must make sure you don’t take heat away from the current radiators.
Can radiators be connected in series?
Connected in series, one radiator’s return water serves as supply for the next. Consequently, the last radiator in the system conveys less heat than the first. To compensate for the loss of heat, radiators must increase in size as they are farther away from the heat source.
How are radiators connected to each other?
Radiators are normally connected to a central heating system via pipes and hot water flows through these pipes and into the radiators themselves transferring hot water into the radiator. As mentioned, this hot water heats the room via convection.
Can I add more radiators to my boiler?
Normally, adding one or two new radiators doesn’t cause any problems, but to be on the safe side, it’s a good idea to check your boiler’s output and make sure it’s powerful enough to accommodate this. See our useful guide for more information about choosing the right boiler for your home.
How do I install two extra radiators?
Quote from the video:
Quote from Youtube video: It's totally up to you you can put a piece of wood exactly on the height where you want the radiator to be lift it up and then you've got an exact measurement for you to put in your top.
Should all radiators have thermostatic valves?
However, while TRVs can, technically, be installed on all radiators, it’s usually a good idea to leave one radiator without a TRV and permanently switched on. Ideally, this should either be a bathroom, which would usually benefit from permanent heat, or the room with the thermostat in it.
Does a towel radiator need a TRV?
However, it’s always recommended to have at least one radiator in your home to have manual valves, without a TRV. It’s common practise for this radiator (or towel rail) to be in the bathroom. The reason one radiator in your home needs to be TRV-free is as a safety mechanism.
Can you put a TRV in the same room as a thermostat?
So all rooms can have trv except where fixed thermostat is. so if setting the TRV in the hall to off but the room thermostat to 28, then the boiler will stay on even if the rest of the house has reached 28 because the hall is cold and the room thermostat can only tell the temperature in the hall, where it is situated.
