Let us now say a prayer for forced air heating systems. They were good for awhile and kept many homes warm through the years, but let’s now leave these noisy relics in the dust and embrace the wonders of hot water heating systems. To say nothing about the ease of control, hot water heating offers a more evenly held heat and a more palpable heat, seeing as it is based on moisture rather than dry air. Hot water heating makes any home more comforting and welcoming during winter.
The furnaces used in hot water heating can be powered by gas, oil, coal, wood, or electric coil. Typically gravity fed or pumped, the heated water in the boiler travels up to the radiators, and as they disperse the heat, the cooler water travels down to the boiler to be reheated. More expensive systems even have hot water tubing under the floorboards, which provides uniform heat.
The radiators, however, are the key component and there are three basic types. First, there’re cast iron radiators, which are actually still very efficient despite their basicness. Radiators fitted with metal covering are similar but often include tubing covered with fins that provide additional convection heat. These fins increase the surface area of the heated parts, and boost energy efficiency. Lastly, there are baseboard heaters, which are more prominent in modern homes and actually provide the most efficient heating on the market. Along with the fins, the placement ensures whole room is heated from the bottom up, which is far more economical.
The issue is that hot water heating systems eventually get air in them and most don’t offer vents. As such, homeowners must “bleed” their hot water heating systems occasionally to ensure efficient use of heat. System valves are easily opened with a key wrench and all you have to do is put a cup, can or bucket under the valve, and open it up. Eventually, water will start running out of the valve, hence the bucket. In multi-story buildings or houses, it’s best to start on the top floor and make your way down, continuing until all floors have been taken care of.
There’s really only one more thing you have to do, and that is to drain out all the water in the system yearly. Begin by turning off the water supply valve, allowing the water cool completely down before moving ahead. Next, find the release valve on the boiler and attach a hose to it. Run the hose outside and completely drain the system, unless you can’t run a hose outside, in which case use drain the system via filling and emptying buckets. This process gets rid of the built-up minerals and rust in the system. Afterwards, open a bleeder valve on the highest radiator and refill the system. This way, your home will remain cozy and you won’t be nervous about the energy you’re using unduly jacking your energy bill up.
