The seven sentences that stop good projects.

“Too good to be true.”

The most common objection — and the best one. The answer comes from the measurement on your own boiler: before, after, using a method developed together with TÜV. If the promised saving is missed, you choose between renegotiation and complete removal with a refund of the purchase price.

“Never touch a running system.”

The attitude is justified. A boiler that has run reliably for years is a value in itself — and every intervention is a risk. That is exactly why the ceramics are built to leave running operation untouched: the shaped blocks are laid into the combustion chamber, not built in. Burner, controls, water side and pressure parts stay as they are.

Installation sits inside a maintenance window you have planned anyway and takes one day. Sites with a redundant boiler keep running on the second plant meanwhile. Since market launch in 2016 there has not been a single damage claim — confirmed by the manufacturer's public liability insurer.

And if it turns out not to fit after all: removal restores the original state. The system that runs today runs exactly the same afterwards.

“My boss simply doesn't pass it on.”

A forwarded link is work for your boss. A good question is not. How to put the topic on the table in one sentence — and why a printed sheet achieves more than any e-mail.

“Engineering blocks it.”

Your engineers have seen a hundred miracle products and rightly rejected ninety-nine. That scepticism protects your operation. What works there: the measurement protocol, the engineer-to-engineer call, and the guarantee.

“Our boiler supplier advises against it.”

One fair question settles it: what does he earn from — your savings or your next boiler? Plus the point usually missed: better flue-gas values often bring older boilers back below the limits.

“No time. Nothing may stand still here.”

Your time input is ten minutes, the downtime a single day — inside the maintenance window you have planned anyway. Sites with a redundant boiler simply run on the second unit.

“We have no budget.”

The budget is already burning — €3,000 to over €10,000 a month in a typical operation, up the chimney. So the question is where you spend it. Two numbers for your financial plan: payback and payment terms.

What a year of waiting costs can be put in figures — here for a reference plant with 3,000 kW and 6 million kilowatt-hours of natural gas a year:

For employees: “I sent it to my boss — nothing happened.”

The same episode in informal German, made for employees and social media. If you pass this page to someone who sees the boiler every day: this is the right version.
