HOT WATER TANKS Water heater rentals are a great solution for many homeowners who have a short-to-medium time frame in their house, own a tenanted property, are looking for a peace-of-mind solution to address their domestic hot water needs, or simply wish to have a clear idea of their monthly house budget over the long term without the worry of heater repairs. Many consumers are confused by which company they actually rent their water heater from, thinking that because the charge appears on their gas bill that they rent from “gas-company”. In fact, most customers in Toronto rent their heaters from Centrica PLC, an international energy services company based in the United Kingdom, which operates in Canada under the brand name Direct Energy™. Although they bill on the gas bill, they are not, in any way, affiliated with your gas utility. Belyea Bros. has a wide range of hot water tank solutions for your family’s needs. We have an excellent rental program providing a comparable rate and great reliable products. We provide a fix rate increase, unlike the other guys who may raise your billing at anytime. TANKLESS HOT WATER Tankless hot water heaters are common in Europe and Japan. They can supply an endless supply of hot water, with greater energy savings than conventional tanks. They are, however, limited in the amount of hot water that can be produced at one time and the upfront costs are higher. ELECTRICAL SERVICE Belyea Bros. Electrical specializes in helping home and business owners in the older neighborhoods of Toronto. We provide electrical service, repair and installation whether it’s diagnosing and fixing a broken outlet, or re-wiring your whole home, Belyea Bros. Electrical is here to help.

General Knowledge Of The Home When it comes to heating and air conditioning there are a lot of factors that can affect the efficiency of the system. Sure, if the ducts are broken and leaking, you are just spewing out good money, but there are other factors like insulation and location that can affect how your units operates. If your home is not adequately insulated or the unit itself is located in the hottest part of the home it is going to have to work much harder, which will reduce the life of the unit, and cost you more in the long run. Here at Wesolveheat , we make sure that our techs are equipped with this type of knowledge in order tackle and solve your problem in the most effective and efficient ways possible. Proper Heat Load Calculations Before Installation When most HVAC contractors suggest that you install a new unit, they automatically just suggest replacing the unit with the same size unit that you already have. For instance, if you have a 3-ton unit, they will just go ahead and make the assumption that a 3-ton is sufficient for the home. Of course, in most cases it is but if you have made additions or changes to the home, a new heat load calculation needs to be performed. We equip our sales staff with the tools and knowledge to perform a heat load calculation, before even giving you a quote on a new unit. Not only does this ensure that you are going to get the proper sized unit, but it can also give you can estimate of what it will costs annually to heat and cool your home with this new unit. This can come in handy when it comes to deciding the type of efficiency you might be looking for.
