This construction project was to remodel a back hallway that contained two closets with bifold doors. The customer felt that the room was crowded and also wanted to create a preparation area for larger family gatherings by adding a counter top and a second refrigerator. Additionally, the conversion of the utility room door to a matching style required some creative to solve the "make up air" issue. This concept is that the heater needs to have a constant source of air so that the unit will still be able to provide fire to heat the hot water! Lastly, we added in the ability to minimize the amount of heat that was kept in the utility room due to the small space and that there was a water heater and a whole house boiler in a small 5x5 room. We installed a thermostat to control the inline exhaust fan which removed the hot air by putting it in the basement which added a thermal layer to the entire first floor. For providing enough makeup air, each time the boiler kicks on to start, an inline fan turns on to provide a steady stream of fresh air to the boiler. From a construction point of view, our solution has been fantastic. It showed that the intelligence of all the tradesman involved provided a cost effective, energy efficient to meet the design needs of the living space.
