Everything you need to know about your heating and hot water system in Heath Town.

Welcome to your new heating system

This ‘Welcome Pack’ will guide you through all you need to know about your home's heating and hot water system to ensure you are set up, comfortable and are benefitting from the district heating and hot water system in place.

Who are Switch2?

Switch2 is the provider of your hot water and heat metering and billing services. Switch2 work with Wolverhampton Homes and City of Wolverhampton Council to ensure that you receive constant heat and hot water to your home.

What is district heating and why am I on it?

Heating and hot water is provided to your home via a system of pipes connected to a central boiler or group of boilers. Instead of an individual boiler installed in your home, you have a heating unit that looks and works very similar.

Benefits of using district heat include:

  • You are receiving low carbon energy from local heat sources that can help reduce emissions. District heating can be highly efficient and uses low carbon fuel sources, such as biomass or waste.
  • District heating can help to tackle the problem of fuel poverty. Replacing expensive heating systems with a district heat network, especially in high-rise apartment blocks, may reduce fuel costs.
  • Lowering the cost of heat – the connection to the local heat source should provide lower cost heat for residential customers, as compared to heat from fossil fuels.
  • If you own your home, you don’t need to buy or service a boiler, Wolverhampton Homes / City of Wolverhampton Council will maintain your heating equipment as required for you.

How is my home heated?

The diagram below shows how your home is heated. 

A central boiler room pumps hot water through pipes to each property connected to the district heating network. There are individual meters in each home which measure the energy you use.

What is the equipment in my home?

  1.  Heat Interface Unit (HIU)

    A heat interface unit (HIU) will look like a boiler and performs a similar job. Heat from the communal boiler is used within the HIU to provide your hot water and heating requirements.
  2. Heat Meter  

    A heat meter is a device that measures how much heating and hot water is -used in your home. Heat energy is measured in kilowatts, shown as kWh on your annual statement. 
  3. G6 Prepayment Unit (PAYG)

    The G6 allows you and us to monitor and measure your usage. We are able to communicate with the unit via a sim card (like the one used in a mobile phone). The G6 has an intelligent in-home display that will show you your heat consumption and usage. (Please see the separate G6 user guide for further details)
  4. Programmer

    The heating programmer lets you set different times and temperatures for different days of the week to suit you.
  5. Room Thermostat

    A room thermostat simply switches the heating system on and off. It works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostat setting and switching it off once this set temperature has been reached.

Pay-as-you-go (PAYG) customers – what does this mean?

Because you have a G6 pre-payment unit you will not receive a monthly bill from Switch 2 - instead you are fully in control of your heating and hot water supply and consumption.

You need to add credit to the unit to make your heating and hot water work.

There are a range of flexible top-up options for you – please have your Switch2 payment card handy when topping up or buying credit:

Heating Costs Payable 

City of Wolverhampton Council operates the district heating scheme on a ‘not for profit’ basis.

All energy costs associated with the district heating scheme, including the standing charges, are recovered using an all-inclusive ‘variable’ kilo watt hour (kWh) rate.

The method used for calculating your kWh rate is to gather all the costs of operating the scheme and apportion these costs by the number of properties at the site.

Please note:

  • This rate will be reviewed annually to ensure costs are correctly attributed to residents.
  • There is no need to read the meter / provide meter readings as they are collected remotely from the heat meter
  • There is a charge of £5 payable for lost or replacement payment cards

Annual Statement (for PAYG customers)

You will receive an annual statement from Switch2 for your records which tells you your metered charges and annual consumption for the year.

Sample of annual statement:
