Proper insulation of hot water pipes has many benefits for any home. It helps to retain heat, save on energy costs, and maintain the temperature of the water as it flows through the plumbing system.
Saves heat and energy
Bare hot water pipes without insulation allow the heat inside to dissipate easily. Insulation acts as a barrier to prevent radiant heat loss when hot water reaches faucets and appliances. Reduced heat loss means that the water heater does not have to work as hard to maintain the temperature. This directly translates into lower energy consumption and lower energy bills. Proper pipe insulation can save 5-10% of water heating costs.
Maintains the temperature of hot water
Insulated pipes also keep water hot as it travels through the water supply. Uninsulated pipes cool hot water quickly, so it becomes lukewarm when you’re about to use it, especially if the taps are far from the heater. This leads to wasted water, as several gallons usually go down the drain while waiting for hot water. Insulation allows water to stay consistently warm even in remote taps.
Reduces condensation
In addition to retaining heat, insulation helps eliminate condensation problems on pipes. Hot pipes can accumulate moisture, eventually leading to corrosion, mould, and potential leaks. Insulation keeps the temperature close to the ambient air temperature to prevent condensation from forming. It also makes the pipes safer to the touch to prevent accidental burns.
Increased efficiency and comfort
Improving energy efficiency through insulated pipes also improves comfort. Water will come to your tap warmer, which improves the performance of your shower, dishwasher, and other appliances. You’ll spend less on your monthly bills, which you can use for other upgrades or investments.
How to insulate water heater pipes on your own?
If you want to insulate your pipes, the process is relatively simple. You can purchase pre-made polystyrene foam pipe insulation at your local hardware store. These insulated tubes fit directly over the existing pipes, making installation easy.
Measure the diameter of the hot water pipes and select the appropriate size of insulation to ensure a snug fit. Secure the insulation with latex-free foil tape wrapped around the seams. Remember to also wrap elbows, fittings, and valves. Use suspension straps for insulated pipes to avoid squeezing the insulation if the pipes are suspended from beams or joists. For additional protection, wrap larger pipes with insulation before placing the pipe coupling on top.
