Setting Up Your HeatCore C1

Your HeatCore C1 gas combi boiler (MV-HC1-32C) has been installed by a Gas Safe registered engineer. This guide walks you through the essential homeowner setup steps so you can start using your heating and hot water straight away.

Step 1: Check the system pressure

Look at the pressure gauge on the front of the boiler. The needle should sit in the green zone, between 1.0 and 1.5 bar when the system is cold. If the pressure is below 1.0 bar, you will need to repressurise the system using the filling loop before continuing. If it is above 2.0 bar, contact your installer.

Step 2: Set the time and date

Press the menu button on the boiler display, then navigate to Settings > Time & Date. Use the arrow keys to set the correct time and date, then press OK to confirm. An accurate clock ensures your heating schedules and timer programmes run at the right times.

Step 3: Set your heating temperature

Press the heating key (radiator icon) on the display. Use the up and down arrows to set your desired central heating flow temperature. For most homes, 55°C is the recommended starting point — this keeps the boiler in condensing mode for maximum efficiency. Press OK to confirm.

Step 4: Set your hot water temperature

Press the hot water key (tap icon) on the display. Use the arrows to set your preferred domestic hot water temperature. A setting of 50–55°C provides comfortable hot water while minimising energy use. Press OK to confirm. The boiler heats water on demand — there is no cylinder to wait for.

Step 5: Pair your wireless thermostat (if supplied)

If your installation includes a Monverta wireless room thermostat, you will need to pair it with the boiler. On the boiler display, go to Settings > Thermostat > Pair. The display will show "Searching." On the thermostat, press and hold the pairing button for 5 seconds until the LED flashes. When the boiler display confirms "Thermostat paired," the connection is complete. The thermostat will now control when the boiler fires for heating.

Step 6: Register your product for warranty

Scan the QR code on the label inside the boiler front panel (or on the quick-start card in your welcome pack) to register your HeatCore C1 online. Registration activates your 5-year parts and labour warranty. You will need the model number (MV-HC1-32C) and the serial number from the boiler rating plate. Registration takes less than two minutes.
