Solar Water Heater Price and Savings

A solar water heater has the lowest running cost of any water heater on sunny days. This page explains what affects the price, how much you can expect to save in Malaysia's climate, and how to get the current Pecol promotion.

Pecol solar water heater

What affects the price

  • System size and number of collectors.
  • Tank material: Pecol uses 1.5 mm SS304 stainless steel.
  • Roof type and height (tiles, metal deck, flat roof frame, scaffolding).
  • Pipe length to bathrooms and any plumbing changes.
  • Current promotions: up to 35% off for a limited time.

How much will you save?

Monthly water heating cost, family of 4 (200 L/day)
Electric heaterRM 84
Heat pumpRM 21
Solar (80% sun)RM 17

At RM0.4443/kWh. Solar saving depends on sunshine; the electric backup covers the rest.

With about 80% of heat from the sun, a family of four saves around RM67 a month, or about RM803 a year, compared with electric heaters. Savings are higher in sunny months and lower in the monsoon season.

What a Pecol solar installation includes

  • 300 L SS304 stainless steel pressure tank with zincalume outer case.
  • Two high-efficiency flat plate collectors with low-iron tempered glass.
  • Mounting frame and roof fixing to suit tiles or metal deck.
  • Electric backup element with thermostat for cloudy days.
  • Pressure relief and plumbing connections to your hot water piping.
  • Testing, commissioning and a user briefing.

Optional extras such as longer pipe runs, extra mixing valves or roof access equipment are listed separately in the quotation, so you know exactly what you are paying for.

Running and maintenance costs

On sunny days the system needs no electricity at all. In wet weeks the backup element runs more, so expect higher bills during the monsoon than in the dry season. Maintenance is minimal: rinse dust and leaves off the glass when needed, and have the relief valve and backup element checked every year or two. Pecol supplies spare parts and servicing for its solar systems.

Payback and lifespan

Because the fuel (sunlight) is free, payback depends mainly on how much hot water you use and the electricity rate. Larger families pay back faster. Built with SS304 stainless steel, a zincalume casing and robotic welding, the system is designed for a long, low-maintenance life.
