TTulpe® C-Meister 10 P30/37/50 Eco – Sealed Propane/Butane Gas Water Heater 10 L/min ErP A / Low NOx

The TTulpe C-Meister 10 P30/37/50 Eco is a compact sealed gas water heater designed for instantaneous hot water production using LPG. Depending on the gas supply and configuration, the appliance is suitable for propane G31 or butane G30 at 30, 37 or 50 mbar.

With a nominal water flow of 10 litres per minute, a maximum heat input of 19 kW and electronic temperature control, the C-Meister 10 provides powerful hot water performance from a particularly compact appliance. The Eco version combines ErP energy efficiency class A with Low NOx combustion, a sealed combustion chamber, forced ventilation and a concentric air/flue system.

Sealed combustion chamber

The C-Meister 10 is a C12-type appliance with a sealed combustion chamber and integrated fan.

Combustion air is drawn from outside while the combustion gases are discharged through the dedicated flue system. This means the combustion process is separated from the air inside the installation room.

The appliance uses a concentric 60/100 mm air/flue connection. The permitted flue length is approximately 0.5 to 4 metres, depending on the installation.

10 litres of hot water per minute

Nominal water flow: 10 litres per minute.

Water is heated only when a hot water outlet is opened. No hot water storage cylinder is required, so there is no need to continuously maintain a stored volume of water at temperature.

The C-Meister 10 can operate from a water pressure as low as 0.1 bar.

Maximum water pressure: 10 bar.

Electronic temperature control

The front of the appliance features a digital control panel for setting and monitoring the hot water temperature.

Water inlet and outlet temperature sensors, a water flow sensor, gas proportional valve and electronic controller work together to adapt the burner output to the actual hot water demand.

With a cold water inlet temperature of 15 °C, the technical data indicates an outlet temperature of up to approximately 65 °C at maximum flame and approximately 35 °C at minimum flame under the specified reference conditions.

The actual outlet temperature depends on factors including inlet water temperature, water pressure and flow rate.

Modulating heat output

The burner does not need to operate continuously at maximum output. The heating capacity is adjusted according to hot water demand.

Maximum heat input: 19 kW.

Maximum useful heat output: 16.5 kW.

Minimum heat input: 7 kW.

Minimum useful heat output: 6.2 kW.

Nominal thermal efficiency: more than 84%.

Propane and butane

The C-Meister 10 P30/37/50 Eco is designed for LPG installations.

Propane: G31.

Butane: G30.

Gas pressure: 30, 37 or 50 mbar depending on the appliance version and gas category.

Certain G30 butane configurations use a supply pressure of 28–30 mbar.

The gas type and operating pressure must always correspond with the information shown on the appliance data plate. Conversion to another gas type must only be carried out professionally using suitable approved components.

ErP energy efficiency class: A.

As an instantaneous gas water heater, the C-Meister 10 heats water only when hot water is required. There is no storage tank that needs to be kept continuously warm.

The Eco version combines this on-demand hot water production with modern Low NOx combustion technology.

Electronic ignition and forced ventilation

The electronic ignition, control system and integrated fan are powered from the mains.

Supply voltage: 220–240 V.

Frequency: 50 Hz.

Ingress protection rating: IPX4D.

Solar pre-heated water function

The C-Meister 10 can also be used in installations where the incoming water has already been pre-heated, for example by a solar thermal system.

An inlet temperature sensor monitors the incoming water. If the water is already sufficiently warm, unnecessary gas heating can be avoided. When the inlet temperature falls sufficiently below the selected temperature, gas heating can resume.

This makes the C-Meister 10 suitable for use as an auxiliary or booster heater in systems with solar pre-heating.

Integrated safety monitoring

The electronic controller continuously monitors several functions during operation.

These include flame detection, inlet and outlet water temperature, water flow, fan operation, air pressure/flue operation and overheating protection.

If a fault is detected, the controller can interrupt the gas supply and display a fault indication on the digital panel.

Compact dimensions

Despite its heating capacity, the C-Meister 10 has a particularly compact housing.

Height: 515 mm.

Width: 328 mm.

Depth: 168 mm.

Weight: approximately 8 kg.

With a depth of only 168 mm, the appliance is well suited to installations where available wall space is limited.
