Contractors across Europe trust Donizo to handle their quotes and invoices while they focus on what they do best: their craft.
On most jobs, hard water beats up tankless units. Scale coats the heat exchanger and flow drops. A Tankelsss water heater filter prevents that. It catches grit and limits scale build-up before water hits the heater. In this guide, you’ll learn which Tankelsss water heater filter to use, how to install it, and how to maintain it. We’ll keep it simple: short steps, common tools, and real numbers. Do this right and you’ll cut call-backs, protect warranties, and keep hot water strong.
A Tankelsss water heater filter sits on the cold feed to stop sediment and reduce scale. Pick the correct size (3/4" or 1" ports), fit isolation valves and a bypass, and service it every 3–6 months. This keeps the heat exchanger clean, flow steady, and energy use lower.
Hard water leaves scale. Scale overheats the exchanger, triggers faults, and wastes energy. A Tankelsss water heater filter tackles two jobs: it traps sediment (sand, rust) and reduces limescale. Many contractors find a filter plus scale inhibitor can extend heat‑exchanger life by several years.
Typical tankless units run 150,000–199,000 BTU with flows of 10–20 L/min. Even a thin 1 mm scale layer can cause noisy operation and temperature swings. With a Tankelsss water heater filter on the cold feed, you protect the narrow passages in the exchanger and keep the unit efficient.
Picking the right model matters more than brand. Match water quality, flow, and connection size to the job.
A two‑stage setup is common: a 5–10 micron sediment filter first, then a scale inhibitor. This covers most UK hard water areas and keeps the Tankelsss water heater filter effective longer.
If space is tight, choose a compact clear housing for quick visual checks. Leave 150–200 mm under the sumps for cartridge swaps. Plan the layout so the Tankelsss water heater filter can be serviced in under 15 minutes.
A clean, simple install saves you time on every service call.
Label the date, micron rating, and next service on the housing. This makes your next visit faster.
Service is quick when you built a proper bypass.
A standard service takes 10–20 minutes:
Keeping records helps you plan visits and avoid emergency call‑outs. It also proves you cared for the Tankelsss water heater filter if any warranty issue arises.
A well‑planned Tankelsss water heater filter avoids these headaches and keeps the heater efficient.
Homeowners understand simple value: cleaner water in, fewer faults out. Offer three levels:
Bundle an annual service. Explain that a Tankelsss water heater filter protects the heat exchanger, keeps flow steady, and can reduce descaling visits. When you pitch add‑ons, capture site notes, photos, and voice memos, then turn them into professional proposals. Tools like Donizo let you capture details by voice, send branded proposals, and secure e‑signatures fast. After approval, convert it to an invoice in one click. If you’re also looking to streamline professional proposals, check our guide on clear pricing and scope language. This pairs well with building strong invoice templates and managing project timelines.
Yes. A softener reduces hardness, but a sediment filter still protects against grit that scratches the heat exchanger. Many installers still add a small scale inhibitor after the softener for extra protection, especially with high temperatures.
Start with 5–10 micron. It traps fine sediment but doesn’t choke flow quickly. If water is very dirty, use 20 micron first, then step down later once pipes clear. Watch pressure drop; change the cartridge at around 0.5–1.0 bar.
A properly sized Tankelsss water heater filter won’t, until the cartridge clogs. Choose 3/4" or 1" ports, match flow rating to the heater (e.g., 15 L/min), and replace cartridges when pressure drop climbs.
Manufacturers often expect clean, treated water. A correctly installed Tankelsss water heater filter supports warranty terms. Keep records of install date, service dates, and cartridges used.
Plan every 3–6 months for cartridges or phosphate media, 10–20 minutes per visit. TAC media usually lasts 2–3 years. Adjust the schedule based on hardness, usage, and pressure readings.
A Tankelsss water heater filter is simple protection that pays off. Size it right, install with a bypass, and service it on time. Do that, and you’ll cut faults, keep flow strong, and extend heater life. Next steps: 1) Test water hardness, 2) Pick a 5–10 micron pre‑filter plus scale control, 3) Fit isolation valves and log the first pressure drop. When you quote the add‑on, platforms such as Donizo help you turn site notes into quick proposals with e‑signatures and clean invoices. Put this into your standard install, and your call‑backs will drop.
