Y plan heating system

How does the heating system come on? Most domestic houses in the UK have one of two heating control systems. Both are designed to closely control your heating system.

Here we talk about the ‘Y ’ plan. In the past this was by far the most common setup, as it only requires one valve. Y-Plan heating systems were widely used in older heating systems.

It can still be fitted today, however is not suitable for systems with more than one heating zone. Port Valve Operation. These two valves can be independently controlled and switched, as seen in the example below.

It is used mostly on vented heating systems with hot water cylinder fed by a cold water storage cistern. What is happening when HW is called for there is a loud bang from the 3way valve.

An unvented cylinder is sealed under pressure, and overheating will cause the pressure inside to rise to dangerous levels. Y - Plan Hot water only Central Heating only. WORK MUST BE COMPLETED BY QUALIFIED ELECTRICIANS OR HEATING ENGINEERS.

System Wiring Diagrams.

Y plan with Unvented Hot Water Cylinder. I have a system boiler fitted to a " Y " Plan system, the heating is controlled by the thermastat but the water is on constant. What I would like to know is this energy efficient, i. A Sundial Plan identifies the components that are used to independently control the temperature and heating periods for both space heating and hot water provision. There is often great confusion regarding the wiring of central heating systems.

Hot water can either be delivered to the tank or sent round the radiators. Electrical wiring for central heating systems. This has one inlet and. Connect heating flow pipe-work to A port of valve.

Also had a new cylinder stat. Hi, my knowledge on system boiler wiring is fairly limited and I have a job where I need to install a new hive chan prog. There is also a vent line that releases any air in the system and returns any water or steam to the top of the expansion tank, in the event of the system overheating. What to check if your heating or hot water is not working.

Use this step by step guide to central heating fault finding and fault repair and identify why your hot water or heating is not working quickly and easily. The confusing bit is that. RF programmer, no. Y Plan is based on a single three way valve that either allows the hot water from the boiler to the heating circuit, hot water circuit or both.

At its simplest level, think of a heating system in two parts: the bit that generates the heat, and the bit that distributes that heat around your home.

You should also, at this early stage, understand that heat is required in two forms — for space heating (i.e. keeping you warm) and for hot water (i.e. for showers etc). Commission the central heating system by closing all of the vents on the radiators, filling the system with water and allowing each radiator to vent through.

Activate the heating pump and re-vent the system. Then switch on the boiler and balance the flow of heated water to each radiator by using the lock shield valves. Pump Plan has two independent pump heads and separate wiring centre which is connected to the boiler and controls (programmer and thermostats). What types of heating control systems and boilers are incompatible with Hive Active Heating?

Honeywell SmartFit Controls - this system, sometimes installed to control gas and LPG boilers, is part of the existing central heating system and isn’t compatible with other external heating controls. Hive Active Heating can’t be installed with it unless the engineer removes the SmartFit controls first, including all electrically operated valves. They can be created when you fill your radiator with water and there is a little air left.

Even though the bubbles do not cause any harm, you are advised to remove them. Otherwise, you run the risk of the heating system oxidising.
