Due to the lack of proper insulating materials in buildings in Israel, homes during summers are brutally hot and are freezing cold during winter; almost worse than being outside. Water-based heating systems (properly known as Hydronic Boilers) are the healthiest, most comfortable and cheapest way to heat a home. The dry air from forced hot air systems (properly known as Furnaces) can cause all sorts of health issues. From head pounding sinus infections and colds to legionnaire’s disease, just to mention a few. Boilers come in two fuel consumption styles, gas or oil. Water-based heating systems in Israel consist of either radiators on the wall or radiant tubing in the floor.
