Guide

What to check before installing this boiler

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

Confirm the model and commercial reference, the type of gas, and the supply configuration in the manufacturer's documentation.
Ask a qualified installer to assess the heating and domestic hot water demand; compare measured flow rates at the same temperature difference.
Check dimensions, connections, flue gas evacuation, condensate drainage, and controls compatible with the existing installation.
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: condensing boilers 8000014250

What power does it offer for heating?

It operates from 2.9 to 20.0 kW useful at 80/60 °C and from 3.3 to 21.7 kW at 50/30 °C. The required power is determined by the thermal demand and the emitters of the installation.

Can it supply two showers at 8 l/min?

Two showers of 8 l/min require 16 l/min. The manufacturer states 14.7 l/min with an inlet temperature of 10 °C and a ΔT of 25 K; at an outlet temperature of 35 °C, this difference corresponds to 25 K. If the water exits at 40 °C, the difference is 30 K; the approximate calculation 14.7 × 25/30 gives about 12.3 l/min, which is lower than 16 l/min under those conditions. It is not a certified flow rate from the manufacturer at ΔT 30 K nor a guarantee for two showers.

What do the 3 liters of micro-accumulation provide?

The 3 liters form a small internal reserve to improve the response when opening the tap. They are not a large sanitary tank nor a reserve to maintain two simultaneous showers.

What are its dimensions?

The body measures 740 × 418 × 344 mm (height × width × depth). The final space must include connections, drainage, and service clearances.

Can I control it via WiFi?

Yes, through the compatible MiGo Link accessory, which is purchased separately.

What gas does it use?

It is prepared for natural gas and can be adapted to propane using the parameters provided by the manufacturer. The conversion and commissioning are the responsibility of a professional.

Does the price include installation and shipping?

Includes VAT and shipping to mainland Spain. Installation and adaptations are valued separately. Installation not included.
