HONE Case Study - Portugal

Portugal - Retrofit - HONE Heating & Hot Water System.

  • Please scroll down to the project FAQ at the bottom of this page for more information on this project.
House in Portugal

HONE Heating & Hot Water System.

This installation is our standard HONE residential Heating & Hot Water System, designed to provide heating & hot water to the house all year round. In this location the HONE system will provide nearly all the heat energy required annually. This home is an existing home which makes the installation of HONE very straight forward. The home had a wood pellet boiler and electric hot water heating originally. HONE is now the primary heat source.

HONE energy systems are designed for each unique installation
so join the Revolution.

What HONE system has been installed here?

The system installed is a standard HONE Heating & Hot Water System. The original wood pellet boiler now acts as a backup if needed. The HONE system is the core heating system.

What was the motivation for the homeowner to do the upgrade?

The homeowner was facing significant heating bills for the year as the home is approx 3,000 sqft. in size. The home is primarily built with solid concrete walls as this is important in the home being able to keep itself cool under intense summer heat. This mass keeps internal temperatures down. This has the counter effect of needing more heat in winter. This type of construction is a typical trade off in Spain and other hot countries to balance comfort in both the colder winter and hot summer. The outdoor swimming pool will require significant amounts of heat and all this will come from the HONE system all year round if required.

 

The advantages for the homeowners are a collapsed energy bill, significantly less cleaning and loading of wood pellet fuel annually in addition to a significant improvement in air quality around the house.

Where there any challenges with this installation?

This house was a retrofit, a very simple straight forward project. This project used radiators throughout the building with a large volume hot water cylinder. The existing system was left in situ and the HONE system integrated easily.

What are the savings expected?

This system is designed to do most of the annual heating which is only in the winter months and all the annual hot water 12 months of the year.
