THE INSTANT WATER HEATER
A thankless water heater, what is it?
This type of water heater for sale in Pakistan, also called water heater according to demand, or instantaneous water heater, is particularly interesting from the environmental point of view since it has no tank. It heats the water on demand, only when someone opens the faucet, eliminating the losses inherent in the conventional tank system (where some of the water remains stored along the walls or in the pipes). A rudimentary system consists of an electric element or a gas burner around which fresh domestic water circulates en route to its point of use.

Let’s start with the electric models. Although effective in Europe, Asia and the United States, this is not the case in Canada! This technology is simply not adapted to our climate, the power required for instantaneous heating of water near 0 ° C during the coldest months is very important. It is therefore reasonable under these conditions to prefer the use of gas as a fuel.

Instant gas water heaters can bereveal interesting in Quebec, but not in any condition of use …

An instantaneous water heater, how does it work?
The instantaneous Branded water heater in Pakistan allows the water to be heated at the precise moment of the request, thanks to an electric element or a burner which turns on and off according to whether or not a sensor detects a movement of water caused by water. opening or closing a tap.

The energy efficiency of the gas water heater is generally between 78 and 85% for standard models, that of condensing models – gas also – ranging between 91 and 96%.

The advantages: saving energy and space, at home … and at the dump
Few energy losses; zero consumption in the absence of consumption;
Reduced costs of use;
Compact and easy to use;
Gain space (no need to reserve space for the tank);
No bacterial proliferation;
They help reduce the amount of water heaters in landfills;
They have a long life (over 20 years), compared to conventional water heaters (10 to 15 years);
Hot water on request unlimited, at any time.
The average energy savings would be, according to Protégez-vous magazine, “22% compared to the consumption of a tank water heater. In a typical Quebec house where hot water represents an annual expenditure of $ 310, it is a saving of about $ 70. “[1]

Disadvantages: a high purchase and installation price and some flow problems
High purchase and installation cost (from $ 1,000 to $ 1,500 for the purchase and $ 1,000 for the installation, note that an efficient electric water heater for a family costs $ 3,000);
Volume of hot water available simultaneously quite low;
Electric models create a large load on the network and may require replacing the electrical panel and wiring (an additional $ 2,000);
It can cause a temperature inconsistency if several faucets discharge the water simultaneously;
There may be a delay of several seconds before getting hot water every time the tap is turned on: some prefer to let the tap run continuously;
If the water flow is low (a stream of water running during shaving for example), the water may not be very hot.
Need to change his habits: avoid drawing hot water simultaneously in several places, no longer add cold water to hot water to take a shower or do dishes, etc … The slight time of waiting (a few seconds) to get hot water can also be perceived as a disadvantage.
Why choose a gas instant water heater
Forget the electric models if your budget is limited. Smaller units, priced starting at $ 500, will be unable to adequately feed more than one faucet. To meet the needs of a family, a very powerful model is needed (at least 28 kW), but for a cost quickly rising to $ 3,000, not to mention the possible additional costs for a particular electrical connection …

Indeed such power may require to completely review your electrical installation. Fireplaces with electric heating normally have a 200-amp input at a voltage of 240 volts, which corresponds to a maximum power of 48 kW (200 x 240 = 48,000). With an instantaneous water heater you will certainly have to switch to 300 amps and replace the electrical cable connecting your panel to the water heater, work that represents a significant additional investment (at least $ 2,000).

In these conditions … choose a gas model. The average additional cost is $ 525 according to a study conducted by Gaz Métro, but generally, between $ 600 and $ 1800 to purchase depending on the heating capacity.

How to choose an instant gas water heater?
Instant gas water heaters can operate without electricity on PKBAZAAR.PK Pakistan, but it is mostly low-end using indoor air in the home rather than outside air for combustion. This type of system is unsuitable because it sucks and removes heat from the house, and because an unsealed combustion chamber can pose a risk of carbon monoxide poisoning in the event of depressurization or back-flow of flue gases. .

The higher-end models operate by sealed combustion: one pipe supplies the burner with fresh air from the outside, while another provides flue gas discharge (several configurations are possible). Appliances operating with an ignition pilot are a little less efficient because there is a slight but constant consumption of gas to keep the pilot on, even outside periods of use.

In Europe, where the gas instant water heater has been in widespread use for over 25 years, users have developed the habit of turning off the pilot when the use of the water heater is not required. However, manufacturers now offer electronic ignition devices that eliminate this drawback: make sure that the selected model is equipped with it. Finally, for second homes or in remote areas, an instant water heater running on propane gas seems appropriate.

Price and energy savings
Is it profitable? A Quebec family of four consumes approximately 600 m³ of natural gas per year for heating water, a bill of $ 340 (Gaz Métro data 2009). Considering a reduction in consumption of 22%, the annual saving is $ 75. A study by the Canadian Mortgage and Housing Corporation (CMHC) estimates a gas saving of 230 m³ / year, which at a cost of $ 0.30 / m³ represents an annual saving of $ 69. If the average additional cost of an instantaneous water heater is $ 525, you will make your purchase profitable in seven years! The return on investment time can still triple if you are billed for a first gas installation (the cost varies considerably depending on the mode of evacuation and the installer, but count $ 1,000) and could be close to the life of the system, which is over 20 years old.

To offset this additional cost, Gaz Métro customers are entitled to a $ 250 rebate on the purchase of an instantaneous water heater. The incentive is for ENERGY STAR qualified models with a capacity of 44 kW (150,000 BTU / h) or 51 kW (175,000 BTU / hr) depending on the energy factor.

The installed unit can also operate in “combo” mode (the water heater is combined with a fan coil that allows the heating of the air). The financial assistance granted varies according to the type of device selected. For example, such an Energy Star certified system is eligible for $ 250 for the standard instant water heater and $ 550 for a condensing model.
