• Yes. We have been manufacturing SAVEMAX solar water heaters SINCE 1991.

• Yes. We have been manufacturing Heat Pumps since 2015.

• Solar Water Heaters if properly sized and designed, give hot water round-the-clock for 8 to 9 months every year. Auxiliary electrical heating elements in the tank can take care of the monsoon and severe-winter days.
• Heat Pump water heaters work on 30% electricity consumption when compared with conventional electrical geyser. Heat Pumps are very compact in size and are fully automatic and highly energy efficient.
• Selection of one of these or a combination depends on terrace availability and usage.

• 25Lakh Litres Per Year of Hot Water Systems. We make solar flat plate collectors with ISI mark and we make etc-solar-water-heaters and heat pumps.

• You are welcome to visit us to learn more. We encourage pre-dispatch-inspection when you order your product.

• We import high quality etc-tubes from a trust-worthy-manufacturer. Every tube bears SAVEMAX laser marking as a mark of quality assurance.

• Yes. They do need maintenance. Preventive and Routine maintenance.
• We have installations as old as 30 years working till date.
• Irrespective of tank material, the TDS, the hardness, the dissolved chemicals such as chlorides, fluorides, carbonates, nitrates, in water, affect all tank materials and eventually, performance and life of solar water heater.
• Good quality water with total hardness less than 100ppm and chlorides less than 30ppm is necessary for the systems to work trouble free.
• If it is not possible then periodic cleaning of the entire system is essential.
• Once we install systems, we can plan to visit your site once every year and can give you necessary advice for the maintenance requirements.
• This will ensure the trouble-free working of solar heaters for many years.

• Yes. We offer AMC at a reasonable cost. We have team of technicians to maintain your systems on periodic basis or on on-call-basis.

We have used epoxy-coated-mild-steel, galvanized steel, stainless steel. We are giving our suggestions based on our experience and expertise. Let us understand how these tanks are made.

Galvanized Steel tanks (Also called as GI tanks)

• We discourage use of tanks made from pre-galvanized sheets for the following reasons. Let’s understand how these tanks are made.
• Fabricator buys pre-galvanized steel sheet from the market.
• He cuts them in necessary sizes. Because of this the edges of mild steel get exposed.
• He then bends them into a cylinder.
• This destroys the micro-structure of galvanizing.
• Then he welds the shell and side covers.
• Because of this at least 3 inches of area along the welding-line gets destroyed.
• He then tries to paint the inner part of welded tank.
• This is not useful and is not possible to do good painting.
• Then he makes holes in the side covers and destroys the galvanizing further.
• The result is a bad quality tank.
• A better alternative is to make a mild-steel tank and then do HOT-DIP-GALVANIZING.
• In this process also, you cannot check coat-thickness. Pinholes remain.
• Another very important thing about these pre-galvanized sheets is these sheets are not made for making hot water tanks. They are coated 120/150/180/200/300 GSM. This means a galvanized coat of 30/37/45/50/75microns. This is not enough and is damaged while folding, bending, welding!!!!!!!!!!!!
• To counter early corrosion problems, the fabricator uses 2mm thick tank. By the time it corrodes you will have used it for 3 to 4 years!!!!!
• It is better if the fabricator uses a superior metal.

Mild steel tanks with enamel/porcelain lining.

• These tanks are made from 1.2mm mild steel material and then they are coated.
• Pre-treatment of material surface is the most important thing in this process.
• If the tank (in the whole process of manufacturing) is left with a tiny defect, then the tank is bound to rust and fail.
• It is advised to use a superior metal.

Mild steel tanks with epoxy coating.

• These tanks are made from 3mm mild steel material and then they are coated.
• Pre-treatment of material surface is the most important thing in this process.
• Because of the material thickness and primer and epoxy coats, these tanks last for at least 5 years. They corrode gradually once the epoxy layer gives away.
• It is advised to use a superior metal.

Stainless Steel tanks (SS304)

• As the name says, Stainless Steel is corrosion resistant.
• Stainless steel material as you know is food-grade-rust-free.
• It is four times costlier compared to Galvanized Steel.
• But it is worth using a material which is corrosion resistant.
• Welding of this material is done with SS308L grade filler material and with high-tech-seam-welding and argon-shielded welding process.
• Every tank is fitted with sacrificial anode to make tank corrosion resistant.
• With good quality water or with periodic descaling, these tanks last very long.

So, it is better to use a superior material such as Stainless Steel
