Live Hot Water Metering for Commercial Buildings

Without real consumption data, sizing decisions frequently lead to oversized equipment that wastes capital, or undersized systems that struggle on peak demand days. Adveco’s live hot water metering service gives you verified consumption data taken from your existing system before any new equipment is specified.

Your consumption data is then analysed and used to produce a detailed system recommendation perfectly matched to your building’s hot water requirements and certified to run on your existing electrical supply.

How our metering service works

Getting an installation team on site is the first step. A data logger is fitted to your existing hot water system, usually without any disruption to the building, and left in place to record actual draw off patterns over a set monitoring period rather than relying on assumptions or a plate on the old boiler.

Site visit and meter installation

An Adveco engineer visits, assesses the existing system and installs the temporary meter non-invasively. No disruption to hot water supply.

Continuous data collection

The meter uploads consumption data at 6-minute intervals throughout the monitoring period, capturing every spike in demand.

Meter removal and analysis

Adveco removes the meter within the month. Data is analysed for average and peak usage, weekly patterns and projected costs.

Bespoke recommendation report

A detailed report outlines required kW output, storage size, temperatures, projected annual consumption, kWh, carbon and costs.

What our metering can tell you

Are you are planning a new hot water system or still at the evaluation stage, Adveco’s metering service provides accurate data to answer the questions that matter most.

Gas or electric? Decide whether your new system should remain gas-fired or go fully electric, based on actual demand and electrical supply capacity.
Renewable integration Which renewable technologies are appropriate and what return would be realistic given your consumption profile.
Backup and redundancy Whether your new system needs backup capacity to cover peak demand or primary system downtime.
Accurate system sizing How large your new system really needs to be and whether your electrical infrastructure can support it without upgrade.

Metering cost and service incentive

The live hot water metering service is charged at a set consultant engineer fee. If you purchase a recommended hot water system from Adveco following the metering report, a proportion of the metering fee will be deducted from your new system price.

For customers who go on to buy a new system from Adveco, the metering service more than pays for itself.

London Fire Brigade

Adveco provided live hot water metering data as part of a planned decarbonisation project for the London Fire Brigade. By accurately metering consumption before new systems were specified, the LFB were able to confirm correct system sizing and get an accurate picture of the carbon and cost savings they would achieve by upgrading.

Results included verified system sizing, confirmed electrical headroom and projected carbon reduction modelled before any capital was committed.

Frequently Asked Questions

What is live hot water metering?

A service that fits a temporary data logger to your existing hot water system, capturing real consumption data before any new equipment is specified. Rather than sizing a replacement on assumptions or the rating plate of the old system, the recommendation is based on how the building actually uses hot water.

How does the metering process work?

Four steps: an Adveco engineer visits and installs the meter non-invasively, the meter uploads consumption data at 6-minute intervals throughout the monitoring period, Adveco removes the meter within the month and analyses the data, then you receive a bespoke recommendation report.

Will installing the meter disrupt our hot water supply?

No. The meter is fitted non-invasively to the existing system with no disruption to hot water supply, and the same applies when it’s removed.

How long is the meter left in place?

Adveco removes the meter within the month of installation, having captured continuous 6-minute interval data throughout that period.

What does the recommendation report actually tell me?

Required kW output, storage size, temperatures, projected annual consumption (kWh), and projected carbon and cost figures, plus answers to the bigger decisions: whether to stay on gas or move to electric, which renewable technologies suit your consumption profile, whether you need backup or redundancy capacity, and whether your existing electrical infrastructure can support a new system without an upgrade.

How much does live hot water metering cost?

It’s charged as a set consultant engineer fee. If you go on to purchase a recommended system from Adveco, a proportion of that fee is deducted from the new system price.

Is metering only useful if I've already decided to replace my system?

No, it’s designed for either stage, whether you’re planning a new system already or still evaluating your options, the data is the same either way and helps you decide rather than assuming the decision’s been made.

Has live hot water metering been used on a real project?

Yes. Adveco used it as part of a planned decarbonisation project for the London Fire Brigade, confirming correct system sizing, electrical headroom, and projected carbon reduction before any capital was committed.
