How to Size Your Unit (Flow Rate & kW)

Undersizing causes cold shocks. Oversizing wastes power. Calculate your peak demand by adding the flow rates of fixtures you might run at once. A standard shower pulls 6 to 8 liters per minute. A kitchen faucet uses 3 to 4 liters. For a single bathroom, a 12 kW electric unit or a 24,000 BTU gas heater suffices. Whole-home coverage in villas demands 24 kW electric or 36,000+ BTU gas systems with 18 to 24 liters per minute output. Check your local water temperature too. Winter inlet water in Riyad

What is a tankless hot water heater?

A tankless hot water heater is an on-demand system that heats water directly as it flows through the unit. It eliminates storage tanks, saves space, and reduces standby energy loss.

How much does a tankless hot water heater cost in Saudi Arabia?

Electric models range from 350 to 1,200 SAR. Gas units span 800 to 3,500+ SAR depending on flow capacity and condensing technology. Installation fees are typically included with premium purchases from YouMats.

What size tankless water heater do I need for a villa?

Whole-home coverage generally requires 24 kW electric or 36,000+ BTU gas systems. These deliver 18 to 24 liters per minute, supporting multiple showers and kitchen taps simultaneously.

Do I need a gas line for a tankless heater?

Only if you choose a gas model. Electric tankless hot water heater units connect directly to your 220V/240V main panel and require no exhaust venting. Gas systems need proper piping, pressure regulators, and ventilation.

How often should I maintain a tankless water heater?

Flush the heat exchanger annually using a descaling solution. In areas with hard water above 200 ppm, biannual maintenance prevents flow restriction and extends unit lifespan.

Are YouMats tankless heaters SASO certified?

Yes. Every unit meets or exceeds Saudi Standards, Metrology and Quality Organization requirements. Certificates are provided with each shipment.
