Questions Answered

Frequently asked questions

The questions we are asked most often about specifying, installing and running commercial coffee equipment, answered without sales spin.

Below are the questions that come up in almost every conversation we have with a new customer. If yours is not covered, or your site has a quirk that makes the general answer unhelpful, get in touch on 01706 216822 or sales@coffeemachinehq.com and we will answer it properly.

Should I choose a bean-to-cup machine or a traditional espresso machine?

It depends far more on your staff than your coffee. A traditional espresso machine gives a skilled operator control over grind, dose and milk texture, and rewards that skill in the cup. It also depends on that skill being present on every shift. Bean-to-cup removes most of the variables: the same button produces the same drink whoever presses it. Barista-led cafes usually favour traditional. Offices, hotels, forecourts and venues with high staff turnover usually favour bean-to-cup.

How do I work out what size machine I need?

Count your busiest hour rather than your daily total. A site selling 200 drinks evenly across a long day places far less strain on equipment than one selling 80 in a forty-minute breakfast rush. Then consider recovery: boiler capacity and heat-up time determine whether the fifteenth drink is as good as the first. Group head count, hopper size, milk fridge capacity and waste bin capacity all follow from that peak figure. Tell us your peak and we will size it with you.

Do I really need a water filter?

In most of the UK, yes. Water makes up the overwhelming majority of the drink, so its mineral content affects extraction, crema and flavour directly. It also determines how quickly scale forms inside boilers and pipework. Filtration and softening protect the machine and stabilise the taste. The right specification depends on your local water hardness and the machine itself, so it is worth checking your area before ordering rather than fitting a generic cartridge and hoping.

What does limescale actually do to a machine?

Scale builds as an insulating layer on heating elements and narrows the bore of pipework and valves. The machine responds by working harder to hit temperature, which raises energy use and stresses components. Flow rates drop, shot times drift, steam pressure weakens and eventually elements fail. Descaling an established build-up is far more expensive and disruptive than preventing it. Correct filtration, changed on schedule, is the cheapest maintenance decision available to any coffee business.

How often should a commercial coffee machine be serviced?

Servicing intervals depend on the machine, the manufacturer’s guidance, your water quality and how many drinks you push through it. A high-volume cafe needs attention far more frequently than an office machine making thirty drinks a day. Whatever the interval, daily cleaning is non-negotiable: backflushing, group head and portafilter cleaning, milk system cycles and hopper hygiene. Always follow the manufacturer’s schedule for your specific model, and keep a record of what was done and when.

Is it better to lease or buy outright?

Purchase suits businesses with available capital that want to own the asset and avoid ongoing commitments. Leasing spreads cost across monthly payments, which helps cash flow and can make a higher specification machine affordable sooner. The trade-offs are the total cost over the term, the length of the commitment, and what happens at the end of it. Consider how long you expect to occupy the site and how quickly your volumes might grow. Speak to your accountant about the treatment that suits your business.

Are ex-demo and refurbished machines a sensible option?

Frequently, yes. A pre-owned commercial machine that has been checked over will often outperform a brand new model from a class below it, because commercial equipment is built to run for years rather than seasons. The things to establish are what work has been carried out, what is included, and what support arrangement comes with it. Availability changes as units come and go, so ask us what is in stock rather than assuming the listing is complete.

Will my existing beans and consumables work with a new machine?

Beans generally transfer, though the grind setting and recipe will need dialling in again, and some bean-to-cup machines prefer a particular roast profile or oil content. Cleaning products, filters and descalers are less interchangeable: using the wrong chemical or cartridge can damage components and affect any manufacturer support you rely on. Cups, lids and glassware are usually a matter of fit and presentation rather than compatibility. Send us your model and we will confirm what suits it.

What do I need in place before installation?

Most commercial machines need a suitable electrical supply, a mains water connection and drainage within reach, plus a stable, level counter that can take the weight. Check the depth of the machine against your counter, and allow clearance above for filling the hopper and below or behind for plumbing. Larger machines may require a dedicated circuit. Confirm the exact requirements for your chosen model with us before delivery so nothing holds the installation up.

How do milk systems differ between machines?

Traditional machines use a steam wand, so texture comes down to the operator. Automatic milk systems draw fresh milk from a fridge and froth it to a programmed recipe, giving consistency without technique. Some machines use powdered milk, which suits unattended and vending applications where refrigeration is impractical. Fresh milk systems produce a better drink but demand disciplined daily cleaning cycles and a fridge alongside the machine. Match the system to how much supervision the machine will realistically get.

What is the difference between filter coffee and espresso-based drinks?

Espresso is brewed quickly under pressure into small, concentrated shots that form the base of lattes, cappuccinos and flat whites. Filter and batch brewing passes water slowly through a larger bed of coffee to produce volume in one go. Batch brewers excel where lots of people want black coffee at the same moment, such as breakfast service or conferences, and they need no barista skill. Many venues run both: espresso for the counter, batch brew for volume.

Do you provide training?

Getting value from a machine depends on the people using it, so we always talk operators through the essentials rather than leaving them with a manual. That covers daily cleaning routines, milk handling, basic dialling in and the warning signs worth acting on early. The depth of training needed varies enormously: a traditional espresso setup in a busy cafe warrants far more time than a one-touch machine in an office. Tell us who will be operating it and we will advise accordingly.

Can one machine cover coffee and other drinks like milkshakes or slush?

Not usually, and it is better that way. Coffee machines are engineered around brewing and steaming, while Shmoo milkshake mixers and slush machines are separate units built for their own job. The upside is that they broaden your offer into the afternoon and through the summer, when hot coffee sales typically dip. If counter space is tight, plan the footprint of all the equipment together before committing to any single machine.
