Gas and conversion: The manufacturer documents natural gas G20 and propane G31. It is necessary to verify the supply configuration and adapt the appliance to the gas of the installation. Compatibility with butane G30 is not offered without explicit documentation of this version. The conversion and commissioning are the responsibility of a qualified professional; they are not included in the purchase. Source 1 ↗ Source 2 ↗

Description

Cointra combines home heating and hot water for taps and showers. When choosing it, both water usage and heating needs are important: a home with multiple showers running at the same time requires a different assessment.

Domestic hot water is prepared when you turn on the tap, without an integrated storage tank. It is important to check how many water points you will use at the same time and the available space to replace the boiler.

What to check before installing this boiler

The choice of equipment does not replace the inspection of the installation by a qualified professional.

  1. Confirm the model and commercial reference, the type of gas, and the supply configuration in the manufacturer's documentation.
  2. Ask a qualified installer to assess the heating and domestic hot water demand; compare measured flow rates at the same temperature difference.
  3. Check dimensions, connections, flue gas evacuation, condensate drainage, and controls compatible with the existing installation.
  4. Confirm the included accessories and the delivery time before scheduling the installation. The online purchase of the equipment does not include installation or commissioning.

Frequently asked questions

Frequently asked questions: V0TPF4AWM condensing boilers

Is it suitable for a 150 m² house?
It can be if the calculated thermal load fits within its 4.7–24 kW at 80/60 °C. For example, 150 m² at 80 W/m² require 12 kW. That area is an assumption, not a certification; the minimum demand and the radiators also need to be checked.
Does it allow two showers of 8 l/min at 40 °C?
With an inlet temperature of 10 °C, it cannot be guaranteed: the two showers require 16 l/min at ΔT 30 °C. The declared flow rate is 16.1 l/min at ΔT 25 °C; the approximation 16.1 × 25/30 gives 13.4 l/min. It is a thermal estimate, not a certified flow rate.
Do you have an 8-liter accumulator?
No. The 8 liters are from the heating expansion vessel. The domestic hot water production is instantaneous; the Comfort preheating reduces the initial wait, but it does not store a sanitary reserve to maintain two showers.
What space do I need in the furniture?
The body measures 70 cm in height, 42 cm in width, and 25 cm in depth. The final opening must allow for the removal of the cover and access to the equipment, as well as accommodate connections and drainage. The dimensions of the casing are not the installation clearances.
When is it worth choosing it over the Supra 24 C?
When more capacity is needed while maintaining the same size: it goes from 14 to 16.1 l/min of domestic hot water at ΔT 25 °C and from 20 to 24 kW maximum heating at 80/60 °C. If the calculated demand is already covered by the 24 C, more power alone is not an advantage.
What changes when moving from this 28 C to the Supra 34 C?
The 34 C rises to 19.5 l/min at ΔT 25 °C and at a maximum heating of 30 kW at 80/60 °C. In return, it requires a depth of 32 cm instead of 25 cm and weighs 31 kg compared to 27 kg. It is advisable to check the space before choosing the higher flow rate.
Does the price include installation and shipping?
Includes VAT and shipping to mainland Spain. Installation and adaptations are valued separately. Boiler only, without flue kit or installation.
